CUPS not recognizing Epson USB-Printer

I'm trying to get an Epson Stylus Office Box BX300F to work with Arch x86_64.
I have followed the CUPS wiki page closely and have installed everything it told me to.
When i connected to http://localhost:631/admin and clicked 'add printer' the USB printer was not listed. dmesg however showed me that the printer is at least recognized to some extent:
[ 2295.813154] usb 2-1: new high speed USB device number 6 using ehci_hcd
[ 2295.951540] usblp0: USB Bidirectional printer dev 6 if 1 alt 0 proto 2 vid 0x04B8 pid 0x0848
[ 2297.177498] usb 2-1: usbfs: interface 1 claimed by usblp while 'usb' sets config #1
I tried blacklisting usblp, but then, after rebooting, it got not recognized at all, so i undid that.
Then i found the printer in the openprint db (link), found the driver that is listed as working perfectly there in the AUR (link) and installed that package. But it doesn't seem to help at all, CUPS still doesn't list any USB printer. I've included the full section of /var/log/cups/error_log with loglevel=debug, hope it helps. Any suggestions on how i can get the printer working are greatly appreciated.
cupsd restarted at 20:31:19 ; i refreshed http://localhost:631/admin at 20:31:24 ; and i clicked 'add printer' at 20:31:30

I have gotten around to give this printer another try and when i connected it and read through /var/log/cups/error_log i noticed 2 lines close to the end that seem to be the problem:
D [24/Aug/2011:12:42:23 +0200] [CGI] libusb couldn't open USB device /dev/bus/usb/002/006: Permission denied.
D [24/Aug/2011:12:42:23 +0200] [CGI] libusb requires write access to USB device nodes.
i checked the permissions, but they seem to be allright:
$ ls -l /dev/bus/usb/002/006
crw-rw-r--+ 1 root scanner 189, 133 24. Aug 12:42 /dev/bus/usb/002/006
$ id
...,7(lp),10(wheel),96(scanner),97(camera)
here is the complete part of error_log from connecting the printer:

Other forum threads i found about libusb permission errors were mostly people that forgot to add themselves to lp and the like. Does anyone know why i get the permission errors and how i can fix it? Any help is greatly appreciated!

Problem adding EPSON USB printer

I contacted Epson's support about this, then did what they told me to in the reply. As you can probably tell since I'm posting this, it didn't work. Here is the email I sent:
"No matter what I do I cannot get EPSON USB to show up under More Printers in Apple's Printer Utility. I can add the regular driver for the printer to my printers list just fine, but when I try to go into More Printers > EPSON USB to add the Border less and Minimized margins (like I had done previously on a PPC based Mac) the option for EPSON USB from the pull down menu doesn't show up. It only shows EPSON FIREWIRE and EPSON TCP/IP. I have tired reinstalling the driver, resetting the printer system and restarting. I have even reinstalled the whole operating system, but even on a fresh install (and the newest driver installed) EPSON USB still didn't show up in the pull down menu. Please help, I need to get border less printing working again.
I am using a Core2Duo MacBook Pro, Epson Stylus Photo 820, The newest version of the driver (downloaded January 1, 2007), and Mac OS X 10.4.8."
Here is what they returned and what I did:
"Thank you for contacting the Epson Connection.
If you are unable to add your printer even after a complete cleanout and
reinstall, please try the following steps to correct this issue.
1. Open Printer Setup Utility (HD > APPLICATIONS > UTILITIES).
2. At the top of the screen, click the words "Printer Setup Utility" and
choose "Reset Printing System" from the pull-down menu. Confirm resetting.
3. All existing printer listings will be deleted. Try adding your Epson
printer again.
This reset makes the operating system clear all jobs and queues and
reconnect to printer drivers currently in the system.
If the printer's plug-in still cannot be selected to ADD, try the following
as well:
1. Begin on the desktop with no windows open or applications running.
2. Go to FILE and down to FIND.
3. In the SEARCH IN option, select EVERYWHERE.
4. Under SEARCH FOR ITEMS WHOSE select NAME and CONTAINS from the drop
down menu.
5. In the search field type COM.APPLE.PRINT and click FIND.
6. Drag ALL the entries that it finds to the TRASH and empty it. Repeat
steps 2-5 to search again and confirm that all COM.APPLE.PRINT files were
removed. (The second search should have no results. If it does, drag the
results to the trash, empty the trash, and repeat the search a final time.)
7. Restart the computer and go back to the Printer Setup Utility to add
the printer. (Note: The COM.APPLE.PRINT preference files will be re-created
upon restart.)
8. After selecting ADD, you will receive a message stating "NEW PRINTER
DRIVERS DETECTED, WOULD YOU LIKE TO RELOAD THE BROWSER?" Click YES.
We would recommend reinstalling the driver and trying to add the printer.
If this fails - Please contact Apple for issues with the Printer Setup
Utility

Does anyone have any advice to solve this?
--Thanks so much.

I'm having problems, too--- my Mac IBoook G4 10.4.8 does not "see"my new Epson flatbed color 58000 dream machine. Now iBook does see the Epson USB cord but not what's at the end of it....
Okay so maybe what has yet to help me, may help you:
I repaired permissions and wow-- there were permissions to repair
I downloaded the shareware, Printer Setup Repair which told me:
"18 missing files/directories found during the verification process. They may be responsible for certain printing problems. Printer Setup Repair cannot replace these items. Please refer to the log file for a list of the missing files/directories. You may need to reinstall OS X to resolve your printing issues. "
I know you did the reinstall (I so don't want to do that, hoping there is some way to just reinstall the printer utility) but perhaps the premissions repair
and maybe even the disk verification may help?
Printer Setup Repair told me things I didn't know-- perhaps it would assist you, too?
Good luck to us. A friend suggested that I may neeed another USB cable---
while my EPSON utility sees the printer, my Mac utility doe not and it may be
about some peculiarities of the USB cable.
Best of luck,

HP Photosmart Plus B209a-m not recognizing any USB drive

When I go to scan to my USB, the USB drive is not recognized as a USB drive. I am using wireless, which works fine. Is there a trick to scanning to a USB?

Hi , Perhaps the USB drive you are using is too large, I believe with a memory card, anything higher than 2 gb is too large, I wonder if the USB drive is the same. I will look into the possibility. In the meantime, Have you tried an alternate USB drive? Let's perform a hard reset. To do so, leave the printer on and unplug the power cable for 1 minute. While it is unplugged, hold down the power button on the printer for 10-15 seconds to release any built up power, then after the minute has passed, plug the printer back in. Also, do you have the printer connected directly to a wall outlet or is it in a surge protector or power bar? Even if you have been using a surge protector/power bar all this time and you feel it is not the cause, please connect it to a wall outlet just so we can eliminate the power source as the root cause. Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector
In this document you will see, ISSUE: Problems or issues may arise when an HP LaserJet series printer is connected to an uninterruptible power supply (UPS), a power strip, or a surge protector ^ This is not limited to Laserjet printers. Please let me know if you are able to get the printer to scan to the USB memory device and we can continue from there.

still nothing.

Did you reinstall itunes, using a new download from the Apple homepage?
Is your ipod showing in the system profiler/ usb highspeed ports?
Did you already reset the ipod by holding the sleep and home button until the Apple logo comes up?

Aluminum Keyboard Sometimes Not Recognized By USB Port

I have an Aluminum wired keyboard that occasionally isn't detected by my Macbook in both Windows XP (Boot Camp) and Leopard. This is an exchanged one because the first one also behaved this way. I'm not using the extension cable. I have a USB wireless mouse plugged into one of the keyboard's USB ports and a flash drive. When the keyboard isn't detected, the mouse doesn't work (no lights on the receiver, can't connect), but the flash drive gets recognized. I've also had the keyboard not be detected without the flash drive so I know that it isn't the issue.
When it isn't detected I have to disconnect and reconnect the keyboard multiple times until it randomly starts working. Once it works, it doesn't stop working, though after going to sleep it occasionally disconnects itself on startup. All the function keys work properly and there's no updates available...is there anything I can do about this?

I've seen the very same problem. In my case I have a wired Mighty Mouse attached to one of the USB ports on the aluminum keyboard. Every time I plug it in -- not recognized first time. Second time -- success. Highly annoying.
Unfortunately I don't have a solution for the problem.

Device not recognized via USB

Hi, i have iPad1 fw4.3 that is out of warranty now. It worked fine.
Suddenly neither windows 7 nor lion would recognize it when connected with usb.
Windows 7 throws "USB device not recognized" message, Lion does nothing.
Im aware of many threads on this subject but nothing helped.
As i'm a game developer i need ipad to test my games, and without usb connection it is useless to me.
I cant afford another one so it's quite important to me.
I'm also form a country not supporded by apple so there is no place where i could take it for service.
iPad is charging fine and works fine.
It shows like "Unknown device" under windows device manager.
Not detected even in Recovery mode, so i cant restore. Any other way to update fw ?
Tried with 3 different cables that work with two ipods on every usb port.
Tried on 3 different windows 7 pcs.
Tried with a fresh install of lion.
Tried leaving all devices unplugged for some time.
Tried disabling network adapters everywhere.
Tried reinstalling itunes, deleting plists and kexts multiple times.
Any thoughts ? Thanks

Update for those interested with similar problem.
Tried DFU, wasnt detected in it also.
Not sure but it seams it is detected when i do a settings reset > connect to a wifi network > do a settings reset
But when its detected it always disconnect itself after 5-10 second unless i do something with it. Its like it disconnects after a 5sec idle.
So, as soon its detected and itunes shows up i start backup to give the device something to do.
That gave me enough time to select ios5 ipsw, itunes to unack it and start the update.
The update went fine, ipad didnt disconnect itself during the procedure.
Unfortunately even though im on ios5 and did full erase the problem persists :/

IPOD not recognized via USB - A lot of trouble shooting already done.

I got a new 80GB iPOD to replace the 4th gen 40GB that just died (HDD issue). I cannot get the computer to recognize it via USB. I had the same problem with my 40GB via USB, however it would usually work via firewire. This new one will not let me use firewire, so I am forced to try to resolve the issue. I know this has come up before on here and I spent about 3 hours last night going through old 'USB Device Not Recognized' posts, but could never find anything similar. This is where I stand. Any help would REALLY be appreciated, because I am pulling my hair out over this.
All previous Itunes have been deleted and Itunes 7 has been installed. This is on WIndows XP Pro.
1. I know it is not a defective IPOD or USB cable because I brought them to work (a non Itunes machine) and plugged it up. IPOD was immediately recognized as IPOD /USB Mass Storage Device.
2. I know it is not the USB port at home because I plugged other devices (Klipsch Promedia speakers / Mouse / Keyboard) into the same port and they worked. Incidentally, this is a front USB port, however, I get the same result if I use a rear port.
3. It is not recognized in Itunes or in 'My Computer'. Only recognized as 'unknown device' in Device manager.
When I plug it up at home, it goes through all the 'new hardware detected' crap and then 'you new hardware is ready to use', but then after about 3 seconds, I get the 'USB Device Not Recognized....USB device has malfunctioned ....'. message. If I go to device manager and uninstall it and then retry. I get the same thing. Even f I reboot between tries.
So, I have pretty much ruled out a hardware problem. I think I read on here somewhere (or a link from Apple) that there was a Microsoft hotfix issued for this issue last year sometime (I think it was a SP2 compatability issue), however, I cannot find the fix. The link I had talks about the hotfix, but there is no file. Also, since the issue first appeared last year, I would think it has been resolved in one of the updates since then.
PLEASE help me out if you can. Thanks!

Here is what worked for me:
My usb hub, being usb2, was too fast. I moved the wire to a usb port directory on my pc. That is a usb1 port which is slow enough to run your snyc.

Mypassport Wireless not recognized through USB on my Mac

I can connect to my Mypassport Wireless fine, but it's not seen through USB on my Mac. I've done a manual reset several times. And the Lock setting is off. Can anyone help? Thanks.

Btw, it's been working fine on both my two Macs for the past week since I've bought it. I've also been plugging it into the USB port of the laptop while powered on and Finder recognized it right away. Now, all of a sudden, neither laptop can see it through USB. I've tried the manual reset, and then powered it down, plugged it into the USB port, and it automatically wakes up, but Finder doesn't show it. Please help. Thanks.

CUPS don't detect USB printer

I have 2 usb printers. An old hp deskjet and a new samsung ML-1640.The first works fine with hplip dirver. For the second I have installed the official Samsund driver via AUR. But CUPS don't see it. It is recognized by the kernel. I see /dev/usb/lp0 device created (root.lp rw-rw---) but still nothing in CUPS .
After searching similar problems on the net I have found a hint that changing permissions on the lp0 device can solve the problem. So chmod +rw lp0 and it WORKS.
But evidently after turn off, turn on of the printer lp0 will have its default permissions again. I tried to find the cause of the problem by comparing the system behavour with my printers. I found that it's identical. The devices are created with the same permissions.
I found also that changing the group of the device to nobody or owner to daemon have the same effect as chmod +rw (it works).
Anybody have an idea why this happen and how to fix it definitively ?
Last edited by artiom (2009-02-10 10:44:43)

Most printers of that class **do need** a slight udev tweak for making them work. Is not wrong to set a +rw on /dev/lp0, but if I were you, I would set a 0660@/dev/lp0 only if it matches your printer.
Maybe something like:
ACTION=="add", SUBSYSTEM=="usb", SYSFS{manofacturer}=="Samsung", MODE="0660", GROUP="lp"
Might help. Obviosly, you need to tweak that rule to your own needs, and **don't forget** to add yourself to the lp group.

What would cause an iPod Nano to charge while connected to a 1.1 USB hub, but not be recognized by Windows or iTunes?
My brother connected his Nano to a USB keyboard port, and has lost it's charge. I've been able to get it to charge on my 1.1 USB hub, but not a 2.0 USB connection. The iPod is also not noticed by Windows or iPodServices.
I put the iPod into Disk Mode and tried all five 2.0 USB ports on my motherboard. It will only charge on the USB hub, but again, won't be recognized by iPodServices.
Intel Pentium D 320 Windows XP Pro

I have the exact same issue. Did you get it resolved. I have a replacement Nano and I think that is messing it up. I was going to send it back to Apple, but they wanted to charge me another $40.00. That would be now $80.00 to repair this piece of crap. So I am asking you if you got resolution.

Zen Xtra not recognized by USB p

When i hook up my zen Xtra (60gb) nothing is recognized by the usb port. it did work, before i downloaded the new driver, and now it doesn't see anything on the port. i tried a different usb port but it still doesn't see anything. any suggestions?

Tried a disk cleanup on the player? To run a Disk Cleanup you need to access the Rescue Mode. To access the Rescue Mode hold down the play button and KEEP it held down, press the tiny reset switch once, and KEEP the play button held down until the player boots into the Rescue Mode. Choose Disk Cleanup from the menu. Note: Disk cleanup should not remove your tracks. It searches through the disk for files and rebuilds the index, and can be useful for correcting any strange behaviour.
Alternati'vely, if the new drivers broke it have you tried installing the drivers from the CD?

2nd generation ipod shuffle not recognized by usb 3.0 port, 2nd generation ipod shuffle not recognized by usb 3.0 port

Hi,
My 2nd generation ipod shuffle will not connect to any usb 3.0 port. I've tried on to computers -- one Windows XP and the other Windows 7. Any ideas?

Hi
I had the same issue with my Late 2009 Mac mini running Mavericks and iTunes 12. When I connected my 2nd generation iPod shuffle it would blink amber once then do nothing. This seems to be a common problem with the iPod shuffle and newer versions of Mac OS X (10.6 and up) and iTunes albeit with somewhat varying symptoms but the same overall problem syncing the iPod with iTunes.
The predominant go-to solution is to give the iPod more power by either connecting the iPod directly to a USB port on the Mac or by disconnecting all other USB devices. On paper this makes sense.
What worked for me, however, was the opposite. After trying to solve this problem for hours (weeks, months), I had success ONLY after adding a low-powered 4-port USB hub to the chain between the iPod and the Mac. I suspect this had the effect of throttling the power supplied to the iPod from the Mac. I was able to perform a restore on the iPod then sync my music over.
I can't tell you much about the USB hub except that it is running at USB 1.1 speeds (12 Mb/sec). In theory a USB 1.1 extension cable should also do the trick. You might even be able to use the USB hub in old wired Apple USB keyboard. I will attach a photo of the hub I used to this post for greater clarity.
I really hope this helps.

Ipod Touch not recognized by USB port on my new radio! PLEASE help?!?!?

Ok, so I just bought a new radio for my car so I can listen to my ipod touch 2nd gen (with the latest 3.0 software) through my speakers. Ok, that's all great, but the problem is that when I connect my ipod touch through the USB port on my new radio, it reads "device error"...
My radio is an Alpine CDE-102. It does have an AUX input, and I can easily get a cable to fix this problem... but I'm wondering why my ipod touch doesn't show up through the USB?!?! And I don't know how AUX input sounds compared to USB input (probably less quality than the USB...)
So, can you help me? I've also connected my ipod touch to my xbox 360 and it shows up as a camera - can't play music... all part of the same problem I guess...
This is a SERIOUSLY annoying problem especially since I just dropped some cash on the new radio which might not even WORK!!! AHHHHH! A problem with the USB cable? Problem with the Ipod? Problem with the stereo? I'm not quite sure what to think...

That is the ONLY cable that will work with that radio:

From reading the manual for your iPod I'm pretty certain the connector is on the rear of your unit.
You can connect an Auxiliary cable to the headphone out on your Touch to the AUX in on the radio but you will have to control everything with the iPod and it will not charge.
The cable is $30, why don't you ask how much they would charge you to install it?
