By defualt when the chips comes up with the driver, if I connect any device on the USB port, the 1761 hub pretends to be self powered which is right if it is a PCI card sitting in a PC. However in an embedded application, I would like it to act as a bus-powered hub. any ideas/suggestion regarding how to change it?

Hi,
I did some experiments using this driver with a PCI evaluation kit for ISP1761, I get data transfer rate between 2 high speed usb devices connected on the 2 ports of the kit in the order of approx. 1.2 MB/sec which is very low in my opinion. I was actually looking for a figure of about 10MB/sec or higher. Any suggestions?
