Hi Alan I'm working on IMX25 platform where I have a USB251xBi family connected to the ehci full speed serial port. IMX25 is capable to manage only full speed port using internal transceiver. Now we found a usb key where I get : [ 2.457831] usb 2-1.2: new full-speed USB device number 3 using ci_hdrc [ 8.593153] usb 2-1-port2: cannot reset (err = -110) [ 9.633234] usb 2-1-port2: cannot reset (err = -110) [ 10.673155] usb 2-1-port2: cannot reset (err = -110) [ 11.732003] usb 2-1-port2: cannot reset (err = -110) [ 12.833154] usb 2-1-port2: cannot reset (err = -110) [ 12.836859] usb 2-1-port2: Cannot enable. Maybe the USB cable is bad?

I have tried all the kernels and having the same problem. Only the 2.6.x from freescale is not affected but this is not helping me. Do you have any suggestion?
