That's very unlikely. > What does this "error -110" exactly mean? 110 is ETIMEDOUT; see include/asm-generic/errno.h. In Documentation/usb/error-codes.txt it says that -ETIMEDOUT indicates either the device failed to respond to a request or a timeout expired before a transfer was completed. > Attached please find the error information. > > Regards, > Xiaofan > > [EMAIL PROTECTED]:~$ uname -a > Linux ubuntu 2.6.14.3 #1 Thu Dec 8 21:02:46 SGT 2005 i686 GNU/Linux > [EMAIL PROTECTED]:~$ dmesg > ... > [17179781.816000] usb 1-3: device descriptor read/64, error -110 Can't tell exactly what sort of error this is because you omitted the preceding portion of the log. > [17179781.992000] ohci_hcd 0000:00:02.0: GetStatus roothub.portstatus > [2] = 0x00 100103 PRSC PPS PES CCS > [17179782.048000] usb 1-3: new full speed USB device using ohci_hcd > and address 37 > [17179782.048000] ohci_hcd 0000:00:02.0: urb d8d32bc0 path 3 ep0out > 5ec20000 cc 5 --> status -110 > [17179782.252000] ohci_hcd 0000:00:02.0: urb d8d32b40 path 3 ep0out > 5ec20000 cc 5 --> status -110 These two errors usually mean the host did not receive a response to a SETUP packet.
