Dear Support Team,
I am currently working with the RG255C-GL 5G RedCap modem. Below is the module information:
ATI
Quectel
RG255C-GL
Revision: RG255CGLABR01A04M4G
I attempted to upgrade the firmware to the new version:
RG255CGLABR01A05M4G
The upgrade process was completed and showed:
“Upgrade module successfully.”
However, after the reset, I began experiencing USB enumeration issues. The following errors appear in the system logs:
- device descriptor read/64, error -71
- Device not responding to setup address
- unable to enumerate USB device
The modem does not appear in lsusb after the reboot, and I noticed the modem is stuck in a reboot loop
The firmware upgrade log indicates that the process completed successfully at 100% before the reset command was issued.
Please help me to solve this issue.
