MQX 3.5 USB problem on MCF52259

I'm using MQX 3.5 on a board based on MCF52259 uC and I use CW7.1.2 to develop final application.

 

I use the uC USB peripheral in order to connect USB sticks to the board, and I have some problem in USB detection.

 

In fact, I tried 10 different USB sticks (various types and sizes) and only 5 of them were recognized by the OS. Some of them were not detected at all (no messages on standard output), instead with some others I saw "Unable to open USB disk" message on standard output. All the USB sticks I tried work well on PCs.

 

I'm thinking about trying to migrate to MQX 3.8. Does anybody know if this is a known issue on MQX 3.5 and if there is some solution?

 

Thanks in advance

 

Best regards
