Linux/OMAP-L138: USB2.0 host driver issue

Part Number: OMAP-L138

Tool/software: Linux

Hi,

We are encountered an issue on USB2.0 Host driver cannot handle more than the max packet size of data at once. Currently the team here is using bulk transfer mechanism at full speed (12Mbps).

For example: 

1. If only one 64bytes of data been received, the USB2.0 Host driver has no issue to handle it.

 

2. If multiple packet of 64bytes of data been received at USB2.0 Host driver, the driver seems like cannot handle it.

 

Would like to check if there is any patch pertaining to this issue?

 

Here are the software version used:

 

- Linux Kernel 2.6.34

- Windriver Linux version 4.x

- MUSB version 6.0 from TI

 

Thanks.
