I cannot communicate via usb with my printer

My intel imac running 10.5.8 stopped communicating with my CX7400 Epson printer today. All of the usb ports work fine with keyboard and iphone and camera but not the printer. I've tried reinstalling the printer software and spoke with an Epson tech who said I had an issue with my usb ports. The printer works fine when I plug it into other printers. Is there a reset process to restore full functionality of the ports or am I possibly facing a hardware issue?

Try these suggestions. Hopefully, one of them will work:

Install the Gutenprint and Gimp-Print for Mac OS X (10.2 and later) drivers.
Boot up from your Leopard Install DVD while holding down the "c" key. Select the language you wish to use, and then choose "Disk Utility" from the menu bar.
Your HD should appear in a panel on the left hand side of the window which opens. Select it and then click on the "repair disk" button in the right hand section of the window.
If Disk First aid is unable to complete the repair you will need to use a stronger 3rd party utility like DiskWarrior or TechTool Pro.
Once this process has been completed restart your computer.

I am assuming you updated to version 5.1.1, not 5.0.1 since no legitimate version of 5.0.1 is available.

HP Deskjet 2540 - connect to pc via USB, can I print from android tablet as well?

Hi,
I've just bought a HP Deskjet 2540 all in one printer.
I have set it up via USB connection to my windows 7 pc, and it is printing fine.
I also have an android tablet. Can I also print from this whilst using the printer via USB on my pc.
Any help on if this is possible and what steps I need to do if it is would be appreciated (I have been reaeding the help section on the website but I am just getting more confused).

Hi @Lesley54R,
You don’t need to have the printer listed with the two different connections unless you’ll be switching back and forth from being connected by USB cable and wireless. You can delete the one you don't think you'll be using.
To print the web page, please use the browser found within the app. I’ve included the ePrint Mobile App FAQs document for your reference.
In addition I’ve also included the ePrint Product Specifications document. This document has the list of supported email programs, file types and print limitations.
Hope this helps!

My new HD with a cloned system and apps won't boot the G5 when installed. The clone drive is being journal formatted via usb with OS9 checked in disk utility. First time around, I didn't check OS9, and the G5 didn't boot from the clone drive. Advice?

My system is a G5 PPC with 2x 2Gig 64bit processors (dual core). 6 gig of ram on board, running OSX 10.4.11. I recently discovered the main drive was actually a laptop drive someone had stuffed in there! (The machine was given to me - yes, really). So I bought a nice new WD Caviar Black 500Gig HD. Hooked it up via usb adapter (G5 won't see it internally). Disk Utility saw it, formatted it with Journal option selected, but not OS9 install.
After that, I cloned the data on the slow laptop drive complete with all the applications onto the Caviar HD.Sure enough, the G5 can see the Caviar HD with everything on it.
However, when putting the Caviar HD in where the laptop drive once was, the G5 would not see the disk at all.
So now, I'm reformatting the drive again but this time with OS9 checkbox ticked in Disk Utility. After this, I will install it into the machine alongside the offensively sluggish laptop drive, and as long as the G5 sees the Caviar HD internally, I will clone from there, rather than via USB hookup.
I hope this way the system will speed up! There's no way the machine is running as it can do with a pokey little laptop drive in it spinning at 5k surely!
I am assuming the Tiger 10.4.11 is genuine (I think it is - the X symbol is present on the folder), but I don't have the original disk...
Any suggestions? Has anyone had this experience?

Hi BDAqua... downstairs away from unit at the moment. It's a Western Digital Caviar Black 500Gig, twin processors, SATA3 / 6, 64Meg cache on-board... nice. Very quite with minimal vibration (slight).
However as I'm here I can announce I've solved the problem! The G5 had an original Seagate Barracuda HDD on board as a slave drive. I backed up the dat off that onto the Caviar Black via USB adapter. Then Disk Utility wiped the Barracuda safely.
Then, I installed SuperDuper! to clone the data from the sluggish laptop master drive onto the Barracuda; I also told SuperDuper! to boot the G5 from the newly image Barracuda.
After it had done the job I switched off the machine (it may well have rebooted - I was downstairs watching England fail at Eurovision Song Contest), took out the laptop drive and started up the G5.
Mercifully, it rebooted fine! All details and programs are intact and functioning right down to my screensaver.
I can report that the machine is noticably (considerably in the case of Logic8 and JamPack) faster and swifter at sourcing data.
Everything is backed up and I now have a speedier G5! Hurrah!!
I now have a spare 80Gig drive to hand in a caddy (originally a spare backup) that was made about the same time as the G5. It's my guess that it would fit the G5 internally and probably be seen ok by the system.
It's worth a try. The Caviar Black will have to go into a caddy and become my backup disk. It has a clone of the OS and all apps, so if something goes badly wrong, I'm safe.
Just a thought: The more advanced Leopard and Snow Leopard OS may struggle in G5's because the OS itself may require faster HDD's that cannot go into the G5 normally? I see many reports of Snow Leopard running like a bag of bones in people's G5's. Perhaps it's something to do with data retrieval speeds?
I'm sticking with Tiger!
I hope this story has assisted someone somewhere... and many thanks to all you kind people who offer to help.

IPOD WILL NOT WORK VIA USB WITH MY HOME TEATHRE

When I plug my iPod to my stereo via USB that came with iPod, stereo says no USB device connected and then after few seconds, it starts playing, although, iPod displays same screen as when synching with the Do Not Disconnect logo and cannot stop it from playing and when I disconnect it, I can't turn it off. This also happens occasionally, that I cannot turn it off.
Any help would be appreciate it.

When was the manual written? What constituted "all iPods" one year would not necessarily apply to iPods made later.
Throw away my iPod and get a new one?
I don't believe I suggested anything like that.
You might get better answers if you included the exact make and model of the home theatre system. You should also search the forums using the "Search Discussions" box to see if there are any other threads about your particular brand of home theatre. Also, did you ever check the support site or contact customer support for the home theatre and car stereo?
Best of luck.

Can I sync Mail via USB with my PowerBook?

I have a new iPhone 4S and a PowerBook G4 17" with 2 GB of RAM that is in mint condition. I understand that I won't get e-mail from a Mail account directly on my PowerBook once I convert from MobileMe to iCloud, unless Apple or a third party develops an "app for that". No way do I want to buy a whole new Mac just for iCloud. Given the ability to sync music and photos between iPhone and PowerBook right now via the USB cord for my iPhone, can I also sync my Mail via USB if I upgrade to iCloud on my iPhone?

You may sync your mac with iPhone via iTunes, as always with iPhones, check whether version is compatible with last iOS. Then your iPhone may sync with iCloud. I still have a 12 in PB made in 2004, it works fine with my iPhone, just it is older, the first iPhone on the market, it sill works fine, no need to replace it.
Before testing anything, backyp your data, just in case you make a mistake, always do that.

BB10 Won't Sync via USB with iCal and Contact in Mac OS 10.8

I was able to transfer all of my data from my Torch to my new Z10 using Blackberry Link, but not it will not let me sync my contacts and iCal via USB cable. They "sync to device" tab is greyed out on the menu bar.
In addtion, in spite of the fact that I've done several back-ups of my phone in Blackberry Link, when I plug my phone into my Mac, it indicates that it has never been backed up.
Suggestions?

I have the same issue and from what I've been able to find online, it appears that Blackberry Link does not allow you to sync contacts, calendar and reminders. Check out this link. https://www.blackberry.com/lms/item/0aa163b0-72e4-7055-f632-baf90ad15bca
If this is actually the case this is a major blunder. Everything else about the phone I absolutely LOVE!

My iPad 1 will not communicate via USB to my Mac or PC

When I connect to my Mac, nothing appears in finder and nothing appears in iTunes
When I connect to my PC(win 7), it gives a little tone (same as all peripherals connected via USB), but it is not recognized and nothing appears in the explorer.
Here's what I've already tried:
- rebooting iPad
- restarting Mac
- restarting PC
- "troubleshooting" the unknown device in the control panel of PC
- factory restoring iPad (and then restored it from iCloud backup)
- tested the USB cable
Any other suggestions? Other than this the iPad is working fine.

Pc Suite cannot conect via USB

Hi hope somebody can help. I recently got a 6220 classic and installed all the software including pc suite and all was working fine. It stopped working yesterday now pc suite will not see the phone but it I can connect via mass storage mode to the pc. I have tried uninstalling and removing all the drivers with a registry cleaner but I still cannot get pc suite working. I am using Vista 64.
Thanks.

Finally worked out a solution, its due to the drivers getting corrupted.
If your running Vista you need to run the cmd prompt then type in sfc /scannow this will do a file check.Do this with the phone plugged into the pc in pc suite mode.
Leave it run it will take a while then reboot the pc with the phone still plugged in, it will reinstall the drivers.
That should be it. Ill try it later on version 7.

Can you get online via USB with OSX10.2.1?

I have a G3 iBook running 10.2.1 and a GPRS phone with a USB cable. The Phone works fine with my MacBook. I have tried everything I can think of to get it to work on the iBook, and the only help i've found online was recommending using Bluetooth (which I don't have on the iBook).
Please help!
Thanks in advance

HT3669 Epson SX 535WD Unable to send scans to Mac Book Pro via USB from Epson Printer screen?

Hi,
I have recently updated to mavericks, I am having porblems opperating my Epson sx 535wd scanner? The printer side seems to work fine!
I have downloaded the latest software form the EPSON www site however I am unable to download the Scanner drivers as my Mac tells me it doesn't reckognise the developer?
Do I change the gate keeper settings on the mac to allow this software to be installed or not? (This was recomended by EPSON? )
Also I have some old Epson software Circa 2012 on my Mac , I asume this is no longer required so can I remove it or would that affect the printer?

The problem I'm having is that I can not seem to access the Epson 1280 from my Dell PC, nor can I access the files on the PC via my Mac Book.
I suggest that you check out the following iFelix articles to see if they will help:
- Printing to a printer on an Airport Extreme Base Station or Airport Express from an XP PC
