Sorry for posting again. I am still stuck on this and hoping if someone has seen this earlier in their setup. The kernel I have has folllowing version of musb_hdrc driver musb_hdrc: version 2.2a/db-0.4.8 [cppi-dma] [peripheral] [debug=0] musb_hdrc: ConfigData=0x06 (UTMI-8, dyn FIFOs, SoftConn) Were there any issues with this ? Regards, Neeraj

I was trying out the usb.c which is implemnting the user space driver for gadgetfs. I see this starting out and attaching to musb_hdrc but quckly disconnects. On the dmesg on host I see "usb 1-2: can't set config #3, error -71" On DaVinci side I see DEVNAME = musb_hdrc /dev/gadget/musb_hdrc ep0 configured serial="zhkrox0z6kzvapdzqaao8frx6loyahihsoaiw9uvpiq29h4vhscopaikpcg3zsh" ** Thu Jan 1 00:39:35 1970 gadgetfs: suspended from state 2 SUSPEND gadgetfs: connected CONNECT high speed gadgetfs: disconnected DISCONNECT gadgetfs: connected CONNECT high speed SETUP 80.06 v0300 i0000 255 SETgadgetfs: disconnected UP 80.06 v0302 i0409 255 SETUP 80.06 v0301 i0409 255 SETUP 80.06 v0303 i0409 255 ep0 read after poll: Level 2 halted done Any ideas why this is happening. I have compiled the driver correctly using kernel supplied include files. Regards, Neeraj
