Hi,
I want to use the USB on Davinci as a Serial Gadget Device.
(1) I have built the kernel with USB Serial Gadget support.
(2) I have installed the g_serial.ko module
If I connect my Davinci board to a Desktop (which is acting as USB
host), nothing happens (no new USB hardware recognized). I am wondering
if something is wrong with my set up.
When I load the g_serial module I get the following message:
~ # modprobe g_serial
Loading Module /lib/modules/2.6.18/kernel/drivers/usb/gadget/g_serial.ko
gs_bind: Gadget Serial v2.2 bound
gs_module_init: Gadget Serial v2.2 loaded
~ # gs_disconnect: Gadget Serial disconnected
usb 2-1: new high speed USB device using dummy_hcd and address 3
gs_disconnect: Gadget Serial disconnected
usb 2-1: Product: Gadget Serial
usb 2-1: Manufacturer: Linux 2.6.18 with dummy_udc
usb 2-1: SerialNumber: 0
usb 2-1: configuration #2 chosen from 1 choice
gs_set_config: Gadget Serial configured, high speed BULK config
Is something wrong here? What is implied by "~ # gs_disconnect: Gadget
Serial disconnected"
I also trying ACM support.
~ # modprobe g_serial use_acm=1
Loading Module /lib/modules/2.6.18/kernel/drivers/usb/gadget/g_serial.ko
gs_bind: Gadget Serial v2.2 bound
gs_module_init: Gadget Serial v2.2 loaded
~ # gs_disconnect: Gadget Serial disconnected
usb 2-1: new high speed USB device using dummy_hcd and address 3
gs_disconnect: Gadget Serial disconnected
usb 2-1: Product: Gadget Serial
usb 2-1: Manufacturer: Linux 2.6.18 with dummy_udc
usb 2-1: SerialNumber: 0
usb 2-1: configuration #2 chosen from 1 choice
gs_set_config: Gadget Serial configured, high speed CDC-ACM config
The result is same. The USB host fails to recognize the USB gadget.
Any suggestions?
Thanks and Regards,
Kunal Singh
