USB problems

I have a Belkin USB2.0 2-port PCI installed and a Belkin USB2.0 4-port hub. It has worked fine for a couple of weeks with a Maxtor Onetouch and also other devices (Iriver MP3, Lacie Mobile HD and Archos AV120). I have tried connecting several of these devices at the same time and transferred data between them without any problems.
A few days ago I finally received my DVD-burner, a Plextor 708UF. I connected it to the hub and tried to burn. It failed. Burning both CD and DVD fails even at the slowest speeds.
I have an old Plextor SCSI CD-burner that I still can use withouty problems to burn at 8x speed. With USB I cannot even burn at 4x.
The scenario is always the same, the burner receives an unknown SCSI request and then it just hangs. The same thing happens when reading a CD or DVD.
I tried connecting the burner to the built-in USB 1.1 (VIA K7T266 Pro 2 board) and the burner worked flawlessly both reading and writing (but burning a full DVD took 75 minutes!).
I have the latest VIA drivers, latest ASPI driver, IDE/ATA are at Ultra DMA mode. I have enabled USB legacy in BIOS. The burner has the latest firmware.
Anyone with anymore hint what I could try ?
I believe I could conclude thet the burner works and that the USB2.0 PCI/hub works. It's just putting them together that does not work.

is the hub on ac power, or is it unpowered?

The hub is powered. The CD-burner is also powered.
Could also add that I have no problems ith temperature, it's always between 55-60 C

Thanks to the excellent support from Plextor I think the problem finally is solved. At least I have tonight burned a DVD+R at 8x successfully.
I also now have five consecutive successes with DVD and CD media.
The problem was a mixture of having wrong drivers and for some reason a misconfiguration.
The USB 2.0 PCI used the generic W2K drivers and that actually worked fine for all other devices I had.
The PX-708UF was faulty identified as a SCSI device.
There is a specific driver for the Belkin PCI card but installing that did not help the misconfiguration.
So I had to do the following:
1. Uninstall all USB drivers (Device Manager - USB Controllers). probably unnecessary to uninstall all but I thought it was safer.
2. Reboot and let Windows install the generic drivers again. Now the PX-708 was identitied as USB connected device.
3. Install the Belkin driver.
