Good question. I stumbled about this, too, when I looked at the code how I could apply your patch. Some months had past since I wrote it :-) The code writes to a serial EEPROM, so the 16 bits are sent using only a clock and a single data bit. The EEPROM emulation then takes the single bits and

I used QEMU 0.9.0 to do the testing. All the seven USB disks can work properly in host OS (Linux 2.6), so the USB devices and its interaction with the kernel drivers should be okay. So the problem must be in QEMU USB code. Thanks Xiaoyang -Original Message- From: [EMAIL PROTECTED]
