The EHCI HW can use the qtd_next field instead of qtd_altnext when a short packet is received. This contradicts what is stated in the EHCI datasheet. Also the total-bytes field in the status field of the following TD gets corrupted upon reception of a short packet! We work this around in software by not queueing more than one job/TD at a time of up to 16Kbytes! The bug has been seen on multiple INTEL based EHCI chips. Other vendors have not been tested yet. - Applications using /dev/usb/X.Y.Z, where Z is non-zero are affected, but not applications using LibUSB v0.1, v1.2 and v2.0. - Mass Storage (umass) is affected.
