Problem VT6212 chipset on 4 Port USB PCI Card


After research indicated a PCI 4 x Port USB expansion card using a VIA chipset (VT6212L) was compatible with Ubuntu 6.06 LTS, two were purchased but are not working correctly. The system is built using Ubuntu 6.06 LTS-Server and usbmount has been installed to conduct automatic loading when a usb device is connected.

In an attempt to eliminate problems with the build the following results are consistently reproduced with each of the OS versions listed below:
Version 6.06 LTS-Server installed to hard disk using kernel 2.6.15-26-server
Version 6.06 LTS-Desktop run form a live CD
Version 7.10 Desktop run from a live CD

Conclusion
The card is found by the system at boot-up.

Conclusion
The card's additional USB resources are available to the system


VT6212 installed
External hard disk connected to a USB port built into the motherboard. Nothing connected to the card.

Conclusions
1.External storage devices connected to the USB port built into the motherboard are made available to the user by udev.
2.External storage devices connected to the USB ports on the expansion card are not made available to the user by udev.

My Linux experience is limited and after 2-3 days trying to resolve this problem I would appreciate any help which might be offered. Is the diagnosis accurate? Is udev the problem here? If so can it be configured to work with the card? Has anyone overcome this problem and is able to offer some assistance?

The problem was related to the brand/model of the card rather than the chipset. Substituting a card of a similar type from a different manufacturer immediately resolved the problem. The replacement card worked flawlessly even though it used precisely the same chipset.

INCOMPATIBLE CARD
Manufacturer: Newlink
Model: USB 2.0
On-board ID markings: PAA02014A

COMPATIBLE CARD
Manufacturer: Net-Lynx
Model: UP1604V
On-board ID markings: G170031910020 v2.0 OSP

It seems that not all cards are equal; which makes purchasing with assurance of compatibility an uncertain process.
The use of generic (rather than proprietary) components was part of the design brief for the project. Does anyone have a suggestion to help avoid similar incompatibility issues for future projects with a similar brief?
