problem with usb printer

[Alexander Best]

hi there.

i'm having a problem with my usb printer. it's being recognised as ulpt0, but
i cannot print. i'm using the cups port for printing. i've set
hw.usb2.ulpt.debug=15 and this is the output:

uhub_reattach_port:348: port 2 reset failed, error=USB_ERR_TIMEOUT
uhub_reattach_port:434: device problem (USB_ERR_TIMEOUT), disabling port 2

ulpt_write_callback:203: state=0x1
ulpt_write_callback:203: state=0x1
ulpt_write_callback:203: state=0x2

after turning off the device i constantly get this output:

ulpt_status_callback:328: error=USB_ERR_STALLED
ulpt_status_callback:328: error=USB_ERR_STALLED
ulpt_status_callback:328: error=USB_ERR_STALLED

ulpt_status_callback:328: error=USB_ERR_STALLED
ulpt_status_callback:328: error=USB_ERR_STALLED
ulpt_status_callback:328: error=USB_ERR_STALLED

the cups daemon cannot be stopped (even with kill -9) and none of the lp* apps
work anymore. also i'm not able to attach any new usb devices. so a reboot is
the only solution that worked in order to get my computer fully operational
again.

i'm running:

cheers.
