 Correct. These are "no-name" VIA PCI USB 2.0 controllers. In the past,
 I've swapped several of these (bought more than one year apart - this is
 what you got at the time when buying a USB controller in the area where I
 used to live) between the two Netra machines I administer, and it does
 not seems to be specific to the machine or a specific controller card (in
 the sense that these PCI cards run fine and without hiccups on Linux/ppc
 and Linux/x86).

 These are the kernel-messages:

 uhci0: <VIA 83C572 USB controller> port 0xc00200-0xc0021f at device 5.0 on =
 pci2
 usbus2: <VIA 83C572 USB controller> on uhci0
 uhci1: <VIA 83C572 USB controller> port 0xc00220-0xc0023f at device 5.1 on =
 pci2
 usbus3: <VIA 83C572 USB controller> on uhci1
 ehci0: <VIA VT6202 USB 2.0 controller> mem 0xa000-0xa0ff at device 5.2 on p=
 ci2
 ehci0: VIA-quirk applied
 usbus4: EHCI version 1.0
 usbus4: <VIA VT6202 USB 2.0 controller> on ehci0

 The relevant part of "pciconf -l" is:

 uhci0 at pci0:2:5:0:       class=3D0x0c0300 card=3D0x30381106 chip=3D0x3038110=
 6 rev=3D0x62 hdr=3D0x00
 uhci1 at pci0:2:5:1:       class=3D0x0c0300 card=3D0x30381106 chip=3D0x3038110=
 6 rev=3D0x62 hdr=3D0x00
 ehci0 at pci0:2:5:2:       class=3D0x0c0320 card=3D0x31041106 chip=3D0x3104110=
 6 rev=3D0x65 hdr=3D0x00

 (World and kernel build for the latest 9-STABLE is on its way, first a
 reference kernel without patches so I know what I compare to...)
