Hello all, I am working on a mips based SOC which has usb 2.0 core integrated in. After taking care of memory mapping and other issues, host controller and usb device are able to be recognized. However, I got some SCSI errors so that partition table of the device cannot be read.
I have searched the achive, adding some delays in sd_mod has no effect on that. With some usb key, fails to read write protect flag, too. BTW, I am using linux-2.4.30 tree. Error message is attached. Could you guys shed some light on the issue? Your help is greatly appreciated.
