This is obviously a behavior of PCI adapters. With onboard USB2.0 you can transfer 13Mbyte/s and more. I've got testet three different PCI cards. The ones with VIA or NEC chipset worked fine with up to 8Mbyte/s. There is also ALI with an USB2.0 chipset. But it didn't work under WIN(98/XP). With my Recorder 20 I got only USB1.1 transfers.
