Hi ,
I am now in use of EVM2 board of DM3730 , when I test the USB Host on USB Controller port2,which connected with USB3320. I found the following problem:
1. when I plugged in a USB2.0 disk ,it can be recognized correct.
2. when I plugged in a USB1.0 mouse on Host port2, it can't be recognized . When I removed the mouse , and plugged in USB disk,it can't be recognized, even can't recover anymore
3. I plugged in USB2.0 DIsk, during it is recognizing, I removed it frome the USB, when I plugged again ,it can't be recognized , but for about 10 minutes ,it is recognized again.
I checked the source of the driver ,and can't find any errors about it , then what's wrong with these phenomena?
Hope For Your Reply!!
Thanks!
