usb-serial adapter not recognized after hibernation in gentoo
Hope this is in the right place.. I wasn't sure whether to put this in hardware or software. My gps receiver uses a pl2303 usb-to-serial adapter. On a fresh gentoo install, the pl2303 is recognized correctly and assigned to /dev/ttyUSB0.
I'm using a tuxonice patched kernel (2.6.26-tuxonice) to suspend my system to disk. It seems to suspend okay, but upon resuming I get the following errors in kern.log and dmesg:
Code:
usb 3-1: new full speed USB device using uhci_hcd and address 2
usb 3-1: device descriptor read/64, error -71
usb 3-1: device descriptor read/64, error -71
usb 3-1: new full speed USB device using uhci_hcd and address 3
usb 3-1: device descriptor read/64, error -71
usb 3-1: device descriptor read/64, error -71
usb 3-1: new full speed USB device using uhci_hcd and address 4
usb 3-1: device not accepting address 4, error -71
usb 3-1: new full speed USB device using uhci_hcd and address 5
usb 3-1: device not accepting address 5, error -71
hub 3-0:1.0: unable to enumerate USB device on port 1
lsusb shows my other USB devices as connected, but does not show the pl2303.
The most frustrating thing, is that even after doing a complete reboot (without hibernation) the error still occurs. The only way I have been able to work around it is to completely reinstall gentoo. Of course as soon as I hibernate, the error returns.
Any ideas?
P.S. here is my lspci:
