Hi I'm having trouble getting any usb gadgets to enumerate properly to the HOST computer, the pc just comes up with Unknown device.
Using linux-2.6.37-psp03.21.00.04
When loading the g_serial device and with the musb-hdrc debug turned on (I can't see how to turn on the da8xx module debug or g_serial)I see the following
#modprobe g_serial use_acm=1 idVendor=0x525 idProduct=0xa4a7 iManufacturer=Diagnosys iProduct=DCP_USB
usb_gadget_probe_driver 1752: registering driver g_serial
g_serial gadget: Gadget Serial v2.4
g_serial gadget: g_serial ready
musb_start 968: <== devctl 80
and then when I connect the usb cable
