Comment 18 for bug 283759

My Belkin USB dongle worked flawlessly all the summer until I noticed this bug about two weeks ago (¿8.10?).
I get the same error:

Nov 15 22:03:40 desktop kernel: [76991.204719] phy11 -> rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 2.
Nov 15 22:03:40 desktop kernel: [76991.204720] Please file bug report to http://rt2x00.serialmonkey.com.

However, there's something very disturbing. This happens *only* when I put the dongle on its dock (a photo: http://images.productserve.com/preview/1256/14458469.jpg), which seems to be nothing but a usb extension cord.
I made heavy-duty tests and this pattern repeats consistently. It seems very weird. Does this make sense?

[Only additional difference: the usb connector to which I attach the device is different, for reasons of available space].

Thanks,
