Pulling the USB cable makes InternetCE crash

Open MathisLav opened this issue 2 years ago • 5 comments

The program crashes when the USB connection is closed unexpectedly (cable pulled...).

It only happens after the calculator called usb_SetConfiguration(). From that moment, pulling the cable causes the stack to be corrupted.

It seems that it's more of an USBDRVCE issue but still, it would be nice to find a workaround for this.

Also experiencing the same issue under the same circumstances with ECM device connection.

Make sure you guys are using usb_RefDevice otherwise freed structures are passed to usbdrvce which will cause it to crash.

I tried to use it but it didn't fix the issue unfortunately. Actually, I'm not even receiving a disconnected event as for me. The calculator crashes just after the cable is pulled, in the next execution of usb_handleEvents() I would say.

Hi, Did you find a solution now?

As I said on Ti-Planet, it seems to be more of an usbdrvce issue. See https://github.com/CE-Programming/toolchain/issues/484
