Hello,
I am trying to interface with a HID USB device, on the other side of a
hub. I mention the hub because this problem did not exist or was not
as pronounced in prior testing without a hub.
After power-on, I can not communicate with the device. If I hotplug
the device and restart the program it works.
I tried inserting the code as part of the initialization:
usb_clear_halt(hid->dev_handle,0x81); //if endpoint is 0x81
usb_reset(hid->dev_handle);
But it did not fix the problem. (I don't know how to get the endpoint
number either)
Is there a way to force an equivalent of a hotplug? Get the whole bus
to enumerate itself?
Any help would be appreciated.
TIA
Allen
