Are you using the FunctionFs or the GadgetFS mode ?
GadgetFS mode
So finally got the debug information finally posting now. So I have more information to share.
While running and connected we get these messages
handle_ep0 : Entering...
handle_ep0 : 1 event(s)
handle_ep0 : EP0 CONNECT EVENT
handle_ep0 : Select without timeout
Then repeats below:
handle_ep0 : 1 event(s)
handle_ep0 : EP0 SETUP event
handle_ep0 : Select without timeout
When we disconnect we get the messages:
handle_ep0 : 1 event(s)
handle_ep0 : EP0 SUSPEND event
handle_ep0 : Select without timeout
handle_ep0 : EP0 DISCONNECT event
handle_ep0 : Leaving (ctx_>stop=1)...
Then we get these messages repeating
uMTP Responder : Disconnected
handle_ep0 : Entering...
Then when we plug in again we get these messages
handle_ep0 : 1 event(s)
handle_ep0 : EP0 CONNECT event
handle_ep0 : Select without timeout
Then a repeat of this message 6 times total
handle_ep0 : 1 event(s)
handle_ep0 : EP0 SETUP event
handle_ep0 : Select without timeout
Then after we get this message and it just stops
handle_ep0 : 1 event(s)
handle_ep0 : EP0 SUSPEND event
handle_ep0 : Select without timeout
Can you try the functionfs mode ?
Trying with FunctionFS mode right now. Works perfectly. Can unplug and plug it in anywhere else and connects right away with no issues.
Hi,
On Compute Module 4, when you have a stable connection with a windows machine. If you remove the connection. Then plug it into a new pc or back into the same machine it will not reconnect.
I've traced it to in here
handle_ep0(usb_gadget * ctx)
. It seems to be going in an infinite loop on trying to reconnect with the timeout.tv_sec
