USB 2.0 PCI hub recognized as USB
 
Hi all,

I'm running Debian (2.6.18-6-486) on a small Via EPIA C3-800 board. Onboard are only USB 1.1 ports, so to expand with USB 2.0 I installed a PCI USB hub based on the VT6212L chip.

The problem is that this card is recognized as USB 1.1 hub and I have no clue how to force a correct driver for this card. Google search was not very helpful other then confirming that the VT6212L chip should be supported.

lspci shows:
...
00:11.2 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 1e)
00:11.3 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 1e)
...
00:14.0 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 62)
00:14.1 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 62)
...
The first two being the onboard USB ports, the latter two being the PCI card.

Can anybody shed some light on this? Any help appreciated.
Thanks,
Martin

USB 2.0 uses EHCI; USB 1.0(1) for Intel and VIA uses UHCI; other USB 1.0(1) uses OHCI.

Try "modprobe ehci" as root.

Problem solved?
 
Thanks for your suggestion, but that didn't help.

When I compare my lspci output with others found on google it showed that that everybody with a similar card got one extra device detected on the pci card. (something like 14.2 USB 2.0 etc)

I am assuming that my system is up to date as I regularly run dselect with update. With more googling I found the command update-pciids, I ran that, rebooted and now the USB 2.0 is detected.

It looks like my problem is solved now. The attached USB HDD drives are running at full speed now.

thanks,
Martin
