Sorry about the poor subject line.

I reran the tests using two PCs, one with Intel chipset/uhci
driver and another with SiS chipset/ehci/ohci drivers.

0000:00:07.2 USB Controller: Intel Corp. 82371AB/EB/MB PIIX4
USB (rev 01)
0000:00:03.0 USB Controller: Silicon Integrated Systems
[SiS] USB 1.0 Controller (rev 0f)
0000:00:03.1 USB Controller: Silicon Integrated Systems
[SiS] USB 1.0 Controller (rev 0f)
0000:00:03.3 USB Controller: Silicon Integrated Systems
[SiS] USB 2.0 Controller

The results with usbtest #14 are:
With SiS/ehci, million runs passed OK.
With SiS/ohci or Intel/uhci, the same failure rate as with
isp1160, i.e., few runs out of 1000 fail with the same
-EOVERFLOW error, with data corrupted.

I did not add logs here. If you need them, just let me know.

Unfortunately I have only a single board with the net2280
chip. So, the question is, is this just with my chip/card.
