Hi list,

I have a Prolific Serial Adapter which is working fine in FreeBSD 6.x and Linux.


But on FreeBSD 8.x It frequently disconnects:

ugen0.2: <vendor 0x067b> at usbus0 (disconnected)
uplcom0: at uhub0, port 2, addr 2 (disconnected)
ugen0.2: <vendor 0x067b> at usbus0
uplcom0: <vendor 0x067b product 0x2303, class 0/0, rev 1.10/2.02, addr 2> on usbus0
ugen0.2: <vendor 0x067b> at usbus0 (disconnected)
uplcom0: at uhub0, port 2, addr 2 (disconnected)
usb_alloc_device: set address 2 failed (USB_ERR_STALLED, ignored)
usb_alloc_device: getting device descriptor at addr 2 failed, USB_ERR_STALLED usbd_req_re_enumerate: addr=2, set address failed! (USB_ERR_STALLED, ignored) usbd_req_re_enumerate: getting device descriptor at addr 2 failed, USB_ERR_STALLED
ugen0.2: <vendor 0x067b> at usbus0
uplcom0: <vendor 0x067b product 0x2303, class 0/0, rev 1.10/2.02, addr 2> on usbus0

Any ideas?


regards
tilman
