Also, the traces start out with the computer > reading string descriptors 1, 2, 3, 4, and 6 (in the non-working trace), and > the values of the descriptors are different in the two traces. In the > working trace, the values are: > > 1: "Xiaomi" > 2: "MI MAX" > 3: "d553b4b6" > 4: "ADB Interface" > > In the non-working trace: > > 1: "Xiaomi" > 2: "Redmi K30 5G" > 3: "c2a85d7" > 4: "ptp_adb" > 6: "ADB Interface" > > It looks like you used two different phones for the tests, or one phone with > two different ROMs installed. Is that what you did? > > Are you asking why one phone works and the other phone doesn't? Yes Mi Max works ,Redmi doesn't.

Can I know is there any tool you used to get this info -- You are receiving this mail because: You are watching the assignee of the bug.
