## Summary cdcacm exit wq after copy all received data ## Impact Fix issue: When the SIM CDCACM host receives data, the second packet data reception is incorrect. ## Testing 1. Compile usbhost: `./build.sh sim:usbhost -j8` 2. Start usbhost: `sudo nuttx/nuttx` 3. Compile usbdev: `./build.sh sim:usbdev -j8` 4. Start usbdev: `sudo nuttx/nuttx` 5. Enable usbdev as cdcacm: input `conn 1` 6. In usbhost, input `cat /dev/ttyACM0 &` 7. In usbdev, input `echo hello > /dev/ttyACM0` multiple times. Note that the second `hello` does not display correctly in usbhost. -- This is an automated message from the Apache Git Service.
