Dear all, I was investigating very slow USB speed from my digital camera (24MB in 30 minutes) and stumbled upon this message in the logs:
usb-storage: This device (0686,4006,0001 S 06 P 50) has an unneeded SubClass entry in unusual_devs.h Please send a copy of this message to <[EMAIL PROTECTED]> uhci_hcd 0000:00:1d.0: uhci_result_control: failed with status 440000 Has this anything to do with the slow speed? Here are the logs, more is available on request if that should be necessairy. I hope this can help you. Best regards, ...
