>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.
uhci0@pci0:7:2: class=0x0c0300 card=0x12340925 chip=0x30381106 rev=0x16 hdr=0x00

device = 'VT82xxxxx UHCI USB 1.1 Controller (All VIA Chipsets)'
class = serial bus

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.
