Hi Greg,
Yes, it also happen on 5.16. I tried it with 5.16-rc8.
May I know what do you mean of 'usb trances'? USB protocol analyzer log or
tcpdump packages?
Actually, I do the same test with another Qualcomm modem device (not the same
serials), and issue can't be reproduced with that device. Seems issue comes
from firmware of device. But we can't explain the difference beween Windows and
Linux.
So do you have any advice to confirm whether the issue relate with the driver
or not?
Thanks!
