Subject: [Bug 209411] When retrieving string descriptor from mobile device returns eproto error
Date: Tue, 29 Sep 2020 16:04:58 +0000
Message-ID: <bug-209411-208809-6fQngomn34@https.bugzilla.kernel.org/> (raw)

--- Comment #4 from Alan Stern (stern@rowland.harvard.edu) ---
Maybe the mobile phone just doesn't want to send its string descriptors after
the configuration has been set.  In any case, it seems like you have found a
usable workaround for the problem.

If you want to get more information about what's happening, you can use usbmon
to trace the packets getting sent and received both during enumeration and
while your program is running (see Documentation/usb/usbmon.rst in the kernel
source).
