MC7455 change USBspeed issue

IoT Modules MC/EM Series
1

I am trying to change the usbspeed of a Sierra MC7455 to avoid a USB3 issue. It’s running this firmware SWI9X30C_02.24.05.06 r7040
When I try to run AT!USBSPEED=0 I get an error (per the instructions here) Techship - FAQ - MiniPCIe based cellular modules supporting USB3 are not detected in the host system?

at!entercnd=“A710”
OK
at!usbspeed=0
ERROR
at!usbspeed?at
SUPPORTED:Super-Speed
CURRENT :High-Speed
OK

Hi tylerterpstra,

Welcome you to our community.

Can you try to download the latest Generic SWI9X30C_02.33.03.00 firmware to the module?
You can get it here AirPrime EM/MC74xx Approved FW Packages

Thanks! After updating the FW the commands work as described. Thank you @Donald !
