We are using the USB1T11AM USB transceiver together with the USB Host (USB 1.1) controller of the MPC8270 processor. The OS is Linux 2.4.
We can detect and enumerate a USB 1.1 Storage device, but when we connect an USB 2.0 Storage device there is a failure, the device is not detected at all.
According to the standard the USB 2.0 device shall start as a full speed device, but are there other differences between USB 1.1 and 2.0 storage device?
We checked the signals, they look good.
Thanks in advance, Bert
