This works well under Windows XP, but under Linux I were able to use it only twice, and I'm still trying to reproduce this success.
I've had those successes with old kernel 2.6.3, but I had to make many attempts (plugging/unplugging/rebooting the system) before I were lucky to get Linux detect the USB device at all (and show it in /proc/bus/usb or "lsusb" output).
Now I can't reproduce those successes anymore, and in the meantime I've changed my motherboard twice.
Anyway, on all three motherboards I've observed the following symptom when the USB device wasn't detected: kernel errors going to syslog, telling me about the device not accepting assigned address. I've Googled and found (on http://www.linux-usb.org/FAQ.html#ts6) an advice to try disabling ACPI, APIC, inserting the connector slowly etc. None of that helped.
I've filed a bug in Mandrake's Bugzilla (since I'm doing all this on Mandrake 10.0):
http://qa.mandrakesoft.com/show_bug.cgi?id=8920
You'll find additional data (like output from dmidecode, dmesg etc.) in the Mandrake bug.
I want to signify that I've also tried a vanilla 2.6.5 kernel (not only Mandrake kernels) and the problem was the same.
If you have a similar device, and can share any info/advice about this, I'd be grateful.
BTW for your convenience, here are the typical log messages:
