>Description:
I'm using a Vosoniq XS-DrivePro VP-300, which is basically an external 2.5"HD combined with a cardreader.
The device works perfectly with 500-600kB/s when connected to the internal USB1 port of the mainboard (VIA chipset), and basically works with ~2MB/s on a USB2 port of a DLink DU-520 card (NEC chipset). However, after transferring some data via USB2/EHCI (usually some 10MB), the connection locks up and waits for some kind of timeout (several minutes). After that, transfer is resumed until the next lockup occurs.

Please let me know if I can provide further information to solve this
problem.
>How-To-Repeat:
Just use the XS-Drive with USB2 and transfer an sufficient amount of data.
