USB error - usb 2-4: device descriptor read/64, error -71

toni_uk · 05-18-2008, 05:30 AM

I have a problem with my USB connections. For some resons they are not quite doing what they should. I have a new camera and on my old laptop (running Ubuntu 8.04) it is detected immediately on the old USB 1.0. On my brand new PC also running Ubuntu 8.04 it is not detected. all my other USB devices are running fine apart from the inbuilt USB card reader in my HP PSC1300. For my Camera dmesg is showing the following:

Any help appreciated - don't quite understand why it is not working. Thanks!

found this - anyone here who knows how to disable CONFIG_USB_SUSPEND on Ubuntu 8.04?

Cheers!

hey guys, just put a clean install of Ubuntu back on my computer and of course had the same problem with the USB/Camera. Did a bit of research and found this so damn easy solution on the Mint Forum:

in the terminal type: echo -1 >/sys/module/usbcore/parameters/autosuspend

I was logged in as root - not sure whether necessary. Then just reboot and Bob's your Uncle.

Worked a treat for me.
