USB scanner problems - it's there, then it's gone
Ok, I've seen this problem on other distros too, so Arch must have something in common with them, but I'm on Arch right now, so I'll try my luck here.
I have a Fujitsu USB scanner, sane installed, udev scanner rules file installed. My user is in the scanner and wheel groups.
lsusb finds it fine: Bus 004 Device 010: ID 04c5:10cf Fujitsu, Ltd
USB device looks right: crw-rw-r--+ 1 root scanner 189, 392 Oct 9 15:33 ./bus/usb/004/010
sane-find-scanner finds it fine: found USB scanner (vendor=0x04c5, product=0x10cf) at libusb:004:010
"scanimage -L" works just fine the first time: device `fujitsu:libusb:004:010' is a FUJITSU fi-4340Cd scanner
But only that time, then it fails to find one. If I strace the scanimage binary, it shows me where it's failing: ioctl(12, USBDEVFS_SETCONFIGURATION, 0x7fff94199eac) = -1 ETIMEDOUT (Connection timed out)
When it works the first time, that line of the strace output looks like this: ioctl(12, USBDEVFS_SETCONFIGURATION, 0x7fffc564cb3c) = 0
I even tried compiling libusb 1.0 into /opt/libusb and pointed sane at it, but same problem. I'm starting to think it's a kernel problem.
Ideas?
BTW, this is on a fresh install of Arch done yesterday: Linux groovy9 3.11.4-1-ARCH #1 SMP PREEMPT Sat Oct 5 21:22:51 CEST 2013 x86_64 GNU/Linux
For a plan B, if there's a straightforward way to custom compile my own kernel, I'd like to try a slightly older one to see if I have better luck. This same model of scanner is working fine on a 3.5 kernel, for example.

My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you think it is? It won't recognize any hard drive I put in the machine, so might it be the sata cable?
Boot the Recvoery USB, use Disk Utility to select the internal drive makers namea and size on the left.
Now select erase and select the midde option and click erase, it will take a bit to complete but it's best for the drive.
Now select Partiton tab, click the big box and Options: GUID and then Format: OS X Extended journaled and click apply.
Quit and you should be able to install OS X now with your Apple ID and password.

I have an iMac G-5 and a Lide 80 scanner which I have not used for several months. When I tried to use it, the Cannon toolbox said the driver was not found. I went to Canon and they had me uninstall and reinstall the scanner software to no avail. The same exact problem is happening with my G-4 17 ". I also tried image capture which could not find the scanner and Read Iris 9 which also cound not find it. I checked the system profiler and it is there under USB. It sounds like a problem with 10.4.6. Does anyone have any advice? I appreciate your help in advance.
DonCheck the System Profiler to see if the scanner is connected. Apple menu -> About This Mac -> More Info -> look in the USB section of the hardware items.
If it isn't there, then try a different USB cable between the scanner and the computer.
If that doesn't get it to show upon a refresh of the System Profiler, then it may be a PRAM/NVRAM, or hardware issue.
To see if it is PRAM or NVRAM, see this article:

I thought macs were supposed to just work with stuff like scanners.
I have a Canon CanoScan N670U USB scanner and I plugged it into the Mac and nothing. It is supposed to get its power from the mac as well so its not lighting up or anything.
I've tried the USB ports on the rear and the one on the keyboard and no difference.
I also checked the Canon site for drivers for OS X but nothing stands out.
Any ideas?That's right. the USB port on the keyboard is a secondary port that gets less power than the one directly on the computer. I've experienced this when using some types of USB flash memory pens. Some of them don't work when plugged into the keyboard but work fine plugged into the computer.
Your scanner won't work at all unless you have downloaded and installed the latest drivers for your particular model, from the Canon website. I have to say Canon (unlike Epson) have been very good at updating all their drivers for the latest version of OSX including Intel.
The one problem is that the Canon website is a bit of a labyrinth. You have to find your way through it until you've found EXACTLY the drivers you need for your particular model of scanner, in the correct language.
You may then find that there are actually TWO components you need to download: one to drive the scanner itself, and another to use it (this is called Canoscan Toolbox, or something like that). You'll need to install both.
Once you've done that you should be fine. Rather than low-powered USB sockets it's likely that you need these updated drivers. -
Remote Desktop and remote USB scanner
Hello, We currently use NeatWorks to scan our company receipts and docs. Several of our employees access the NeatWorks database remotely, via a locally installed NeatWorks application, the connection we use to the file is the simple Finder 'Connect to Server'. Because NeatWorks is not networkable, we access it one at a time.
The problem is the Neatworks database is huge, it can take 20 minutes to load remotely.
Our solution to this would be to use Remote Desktop to access our server that has the application and database for a quick load. The problem is scanning.
Can Remote Desktop connect to the users local USB scanner so that the scans go directly to the remote database? If not, is there any other elegant solution to this remote scan problem?
We were hoping to find a networkable program to replace NeatWorks that wouldn't load the entire database, just an index perhaps.
Thanks a million for any input!
JohnCan the NeatWorks application on the server, see, connect to the USB scanner device on the user end.
That would not be a function of Apple Remote Desktop. The NeatWorks software would need to have code to access a remote scanner, either natively or using the Scanner Sharing feature of Mac OS X 10.6 (if that will support the USB scanner you're using). -
My ipod shuffle 4th generation was working fine for a few months. My son then bit the USB charger. I bought a new USB charger, but the shuffle is not charging and not showing up under the devices in itunes. It also doesn't appear in my windows under my computer. Just to note. I also have a new ipod touch. I am able to charge that fine on the same computer using the USB charger. The device (Ipod touch) does show up in windows and in itunes. The shuffle doesn't show in either place.
I have tried to use the apple support page. I went through each step. I made all of my USB drives not shut down, I had my computer on all night to try and charge the shuffle. All I see is a red light that appears on the shuffle for a few seconds when I first connect the USB charger to the computer. Then, nothing. Since this was working a bit ago, I don't think that I have a defective shuffle. The USB charger is brand new, I just picked it up yesterday from the apple store. I have the short one, and the longer cable as well.
Any help that you might be able to give to me would be much appreciated. My daughter is missing listening to her music. Thanks!Instead of "charger," you should call it the "USB cable" to avoid confusion. When started reading your post, I was thinking, how can your son break a USB power adapter (the "charger" that plugs into a wall socket) by biting it...
Since you got the product with the two USB cables at the Apple Store, you have the right replacement (some third-party replacements are for the 2nd gen shuffle and do not work with the 4th gen shuffle). Make sure you are completely inserting the plug into the headphones jack. The fit may be tighter than expected, since the connectors are new.
http://support.apple.com/kb/TS3572
If you tried both of those cables, it would be unlikely that you got two faulty cables in one package. If a new USB device has been added to the computer between the time it worked with the old cable and now, there could be a problem on the USB bus (such as not enough power or a device conflict).
As a test, you should shut down (power off) the computer and disconnect all USB devices (including any hub), except for standard keyboard and mouse (if used). Do this to reset the shuffle
http://support.apple.com/kb/ht1655
Start up computer, run iTunes, and connect the shuffle by itself to a direct USB port on the computer. -
Dear Community,
how can I connect SCSI tape recorder via USB to iMac ?
Is there any adapter/converter on the market now ?
Cheers, MarekThanks Jan.
Actually the reason to use Quantum SCSI tape recorder is to back-up big amount of data (propriety movies footage) both on PC (what is quite easy, using SCSII host adapter with VHDCI 68 connector) and iMac what seems to be not easy. All my search by Google leads to that conclussion, they finished production of SCSI-to-USB or FireWire because somebody stopped to produce chips to covert protocols. So even buying noe second-hand adapter, no guaranty it's still working with Lion (nobody is developing drivers anymore). Strange is, nobody or just a few are using SCSII (Ultra 320) devices (while the transfer is not bad, 320 MBps what is 2560 Mbps, so the only limitation is tape recording (some 80 MBps) not an interface. Using compression mode I can (and I do) record 1,6 TB of footage data. However quite slow, is safe and cheap, comparing with any HD storage solution. USB 2 is much more limited.
I'm using Time Capsule for buck-up. But even 3 TB one day will be full of data, then old back-ups will be eaten by new once, what is not good idea for archives. I'm using another 2TB NAS HD (2x2TB RAID 1), but this is also going to be full soon.
Of course, you are right, the option is another machine (OSX,Win,Linux or Solaris) equipped with SCSII controller. But this requires another machine, just for back-up time to time, and in practice iMac folders must be shared with that small auxiliary machine because amount of data practically excluding even temporary data collection on auxiliary machine. And it must be transfer by wire, not WIFI, my only network. Tape recording is in my case really good, professional solution, isn't it?
Anyway, if somebody has similar requirements as me, and found the solution for SCSI, please let me know. So far, follow Jan's idea, I'm thinking about some embeded mini PC, fanless, equipped with slot for SCSI, with SOME smart system on-board, to deal with iMac for type recording. The option is previous Apple model, but to be honest, I became Mac/OSX user 4 years ago. I fell in love with Mac, but my knowledge about previous models is based on Google....
My desk becomes full of boxes. Do you know how big Quantum TC-L42BX is ? Is very big. And now another box.....another keyboard....another screen... And one small adapter could solve the problem. Eh....
Best regards,

I'm having a problem with my Bose USB sound system that has just recently developed. The system is plugged directly into the back of my Mac Pro desktop so it's not going through any hubs or secondary systems. When I first start my computer the sound works just fine. But after about 10 to 15 minutes of use the sound stops completely - as if the sounds have been turned off. If I boot into Windows 7 using Boot Camp, the sound system there works just fine with no problems at all, so I do not believe this issue is hardware related but is something associated with OS X.
This all started recently after installing Tinker Tool and then realizing that their latest version is not compatible with Snow Leopard. I followed their directions and told Tinker Tool to restore the previous settings and then I removed it from my system. Now, I'm having this USB sound problem. I think it's highly probable to be the cause of my problem.
Is there anyway to reinstall the USB drivers in OS X without reinstalling the entire OS? Or, is there something else I can try to restore the USB function to Snow Leopard? Many thanks for any tips or suggestions.They are plug and play.
I did try unplugging all of the USB devices and then powered off the computer and unplugged it for about 5 minutes as I heard that that sometimes solves USB problems. However, upon reconnecting the problem returned. All other USB devices seem to be working normally - it's only the Bose sound system. I tried plugging it into a different USB port in the back of the computer but the problem continued after about 10 minutes. Therefore, I am convinced this is not hardware related.
At this point I am thinking I need to reinstall OS X Snow Leopard to undo whatever Tinker Tool damaged. Is it possible to just replace the USB drivers in OS X without reinstalling everything? -
Hy guys,
Since i've bought my N78 i've been able to connect the phone via cable only one time. After that, every time i've tryed to connect my n78 via cable my computer doesn't recognize my Phone.
When I plug USB cable in one of the USB ports, Windows XP gives me back an error that says "USB devices not recognized - One or more devices connected to the computer has not worked correctly. Windows is not able to recognize it".
I've reinstalled PC suite thousands of times,but nothing changes.
My phone has the 12.046 software version. I know that there'e a newer version but how I can update it if my PC does not recognize the phone, and hence, PC suite is not able to connect to the phone.
Many thanks for you help
myou have another option in updating via Firmware Over The Air. you can do this by entering *#0000# in the standby screen and selecting Options > Check for updates. if an update is not available over NSU, then it may be on FOTA instead for your product code. this method of updating only takes about three to five minutes anyway. remember to do a hard reset (three-finger hard reset) after updating your phone to the new firmware.
so you can probably update from 12.046 to 20.149 or 21.002. USB connectivity problems are probably due to problems with the USB cable or the computer, i have had no problems at all with USB connectivity in all the time i've had my N78, even under 12.046 firmware.
let us know how it goes.
If you found this or someone's comments helpful or like what that person has to say, please give some Kudos to their post! -
Okay, I'm totally confused.
I have a Canon Lide-30 USB scanner which I have used under Arch Linux many times--but not for 2 or 3 months. However, I was never able to configure hotplug to set the permissions automatically; I always had to become root and manually set the permissions in order to access the scanner as a regular user. Now, of course, the devices are all different (I mostly keep up with the latest release, don't really use testing packages, so I now have kernel 2.6.14).
Here's what's happening:
I plugged in the scanner's USB cable after booting (my machine's been up continuously for a few days, so I would have to shut down to do otherwise).
Loaded the uhci-hcd module ... now /proc/bus/usb is mounted, and it contains a node for my scanner.
Run sane-find-scanner as root:
found USB scanner (vendor=0x04a9 [Canon], product=0x220e [CanoScan], chip=LM9832/3) at libusb:001:002
Run sane-find-scanner as myself: same as above
Run xsane as root: OK.
Run xsane as myself: No devices found.
# chmod 777 /dev/usbdev1.2 (which I think represents the scanner)
# chmod 777 /dev/usbdev1.1
# chmod 777 /proc/bus/usb/001/002
# chmod 777 /proc/bus/usb/001/001
No change. I still can't access the scanner as myself.
By the way, it appears that the hotplug daemon won't start, though I'm not quite sure why. There are no files in /var/log/hotplug. In /var/log/errors, I see
DEVPATH is not set (subsystem pci)
But according to a brief Google search, this is not a serious problem.
So what's the magic formula?Have you read this?

My Aztec 1236 USB scanner stumped Tiger.
Hi. I bought an Aztec 1236 USB scanner used for five bucks. It came with nothing. I was lucky enough to find the model number. It's vintage but the price fit my post-buying-a-mac budget.
I managed to dig up a Win XP driver for it w/ the accompanying photoshop bits (not a plugin, actually had an installer). The scanner works slow, but fine. But I want my PC free to do other things.
But Tiger can't see it when I plug it in, let alone know what to do with it. I tried the Image Capture device browser TWAIN trick--and it ain't showing. I can't find a Mac OS X driver for it anywhere, not even w/ Google.
Anybody know how I can save the hundred bucks and avoid buying a new scanner? Anybody found a Tiger driver for my classy, antique flatbed?I don't know where you get your information but Apple doesn't claim "it just works with everything." No computer can truly make that claim. Apple does, however, provide a list of known compatible devices. Consulting this available information would help you avoid making a mistake by purchasing incompatible hardware.
It's up to the peripheral manufacturer to make compatible drivers. If your scanner doesn't work on a Mac then the problem is with its manufacturer not with Apple.
You purchased a cheap used scanner without knowing in advance whether a driver would be available for the Mac. This is your oversight. Ranting at Apple (which, btw, is not appropriate here) is simply trying to shift the blame from where it really lies. -
I just purchased an HP Envy 4500. It connects to my home WiFi network and prints just fine from Mac and PC computers, iPads and iPhones. However, ever since we opened it it has repeatedly said this when we try to scan: Scanner problem:Turn printer off and then on. If the problem is not fixed, the scanner component is broken and cannot copy or scan. Here are the things I've done to try to see if I can fix the problem that did NOT work:-Turn Envy 4500 off and on several times-Unplug Envy 4500 and plug it back in-Go through the steps on the "HP Print and Scan Doctor Download page"-Download and install the "HP Print and Scan Doctor 4.2" software and follow instructions until it said "The tool was unable to resolve the problem, even after a restart. Go to HP Customer Care for help resolving the issue"-Go to HP Customer Care and check all resources there with no luck At this point I'm assuming the Envy 4500 is defective and needs to be replaced. However, if there is something else I can do to try to fix it before exchanging it I would like to do that. Any advice on how to proceed is greatly appreciated. Mike [email protected]
Thanks for the response. I have tried scanning a few different ways... Every time I try to scan via typing the Envy 4500 IP address in the browser (after enabling webscan in the admin settings) it gives me the following error in yellow text: The printer is busy. Try again later. It says this even though it is not processing any other jobs and the unit is on. If I try to scan from the HP Utility on my Mac (after successfully connecting to the Envy 4500) running the current version of OS X 10.9 I get an error that says: Communications ErrorUnable to communicate with device. Check cables and connection settings. If the problem persists, try restarting your computer and the HP device. If I try to do a test scan in the "Scan to computer " section of the utility within preferences it says: Error testing shortcutThere was an error testing shortcut "Photo (Jpeg)" If I try to scan from the "HP Scan" window of the utility I get the following error: Scanner reported an errorHP Envy 4500 is currently unavailable. Please check if it is turned on and connected, or try again later. After all of these errors I've tried restarting the Envy 4500, unplugging and plugging back in the Envy 4500, and restarting my computer and trying these methods all again with no luck. It's also worth mentioning that after all these attemps I still get the same error on the LCD display of the unit when starting it up or going to the scan section: Scanner problem:Turn printer off and then on. If the problem is not fixed, the scanner component is broken and cannot copy or scan. Is there anything else I can try or is this unit defective and needs to be exchanged for a working model?

Has anyone been able to get a USB Scanner to work with either an Ultra 5/10 or the SunBlades, or other Sun hardware under Solaris 8 or 9? I'm trying to get the SANE backends to work with my Ultra 10 which has a generic USB card installed. The main problem is that there appears to be no device driver for a USB scanner, so no device such as /dev/usb/scanner0 is being created. I have other working USB devices such as a USB hub, a HP printer, and a memory key storage device that are recognized as /dev/usb/hub0, /dev/usb/printer0, & /dev/usb/storage0, respectively. The system does see this USB scanner at boot time as it complains there is no device driver for it.
Thanks for any help given,
Matt EvansHi,
I want to use sane on solaris 9 with a fujitsu ScanPartner 620C.
I've already installed sane and changed /kernel/drv/sgen.conf. When I run sane-find-scanner, the following appears:
found SCSI scanner "FCPA ScanPartner 620C 2.02" at /dev/scsi/scanner/c1t4d0
# Your SCSI scanner was detected. It may or may not be supported by SANE. Try
# scanimage -L and read the backend's manpage.
# No USB scanners found. If you expected something different, make sure that
# you have loaded a driver for your USB host controller and have installed a
# kernel scanner module.
# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.
but when I run scanimage -L, the following error occurs:
No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
May you help-me with this problem?

Hello
Sorry I'm newbie and don't know if We need to make any operation on Mac OSX before unplug a USB SCANNER...
Could we simply disconnect the USB plug ? Is ther any mounting/unmounting process like pendrives?
Thank you.Hi Kappy and eww, thanks for your replies!
I need to hot-swap USB devices, without turn-off my MBP everytime and I don't know if this procedure will damage both sides if I repeat every time.
For example, mouses aren't powered devices then I imagine it's ok to hot-swap.
I made the same question to HP (I use HP 3570c scanner) and I'm waiting their answer.
I like Apple Discussions because seems so friendly geek lounge! Congratulations for all members! -
