Usb pen not working in additional usb port


I have a "super flash drive" 512 mb usb pen. When connecting it to the additional front usb ports, Mepis gives me a read error, and there's no way to let it function. When I switch it to the rear motherboard 2.0 usb ports it works fine.

It might be a power supply problem (the rear ports are directly supplied, whereas the front ones are connected via an extra cable). But that doesn't explain why the pen is working under windoze.

Thanks!

First check it gets recognised as you insert/remove it. In either case this should generate a kernel message which you can see at the end of the output of the 'dmesg' command.

If nothing there you may have the extra ports disabled in the BIOS. Some m/boards at least let you set how many USB ports are enabled.

Yes, the pen is recognised, and the output is:

Code:
usb 1-6: new high speed USB device using ehci_hcd and address 4 usb 1-6: device descriptor read/all, error -71 usb 1-6: new high speed USB device using ehci_hcd and address 5 usb 1-6: device descriptor read/all, error -71
As I wrote, the pen works perfectly if used under window$ (I mean on the front extra ports). It also works under Mepis, but only if I plug it on the back 2.0 ports.
Thanks

Sorry, I never saw that sort of error before. But there is a big thread on a similar problem.

http://www.linuxquestions.org/questi...5&pagenumber=1

and google also shows it's not uncommon. Unfortunately most suggestions seem to be something like 'poke it with a stick until it starts working'. I'm not familiar with your distro so I don't know how much is relevant to your case.
