Hi experts,
I now face a issue with USB host/slave read/write test. The error message on host side as below (around 30% error rate)
[ 352.506963] usb 3-1: device descriptor read/64, error -110
[ 367.736962] usb 3-1: device descriptor read/64, error -110

Both host and slave use 3.02.00.03 GLSDK. Slave is in OTG mode.
Could you please help this issue.
