USB errors when using wifi dongle as an AP

I am working on DM368 Board act as a host and connect with a device(WIFI USB Dongle) that is running as an AP.
The WIFI Dongle loses its connection to WIFI devices whenever the error message is shown.
error message:
musb_ep_program 845: broken !rx_reinit, ep2 csr 0220
musb_ep_program 845: broken !rx_reinit, ep2 csr 0220
musb_ep_program 845: broken !rx_reinit, ep2 csr 0220

I think there is something wrong with musb.
I am using Linux kernel version 2.6.37
