huawei modeswitch message content explained

Post by slavokhire5 » 18 Aug 2022, 15:13

Hi everyone,

I'm trying to work with Huawei E3372h and found many different MessageContent variations.
Like this: (split by bytes for readability):

Code: Select all

55 53 42 43 00 00 00 00
00 00 00 00 00 00 00 11
06 30 00 00 00 00 01 00
00 00 00 00 00 00 00
Does anybody know what exactly these magic numbers mean or have some documents?
The only I know is byte (bit?) 01 responsible for NDIS mode selection

Best regards

Small update. First 15 bytes are Command Block Wrapper for SCSI. More info at https://wiki.osdev.org/USB_Mass_Storage_Class_Devices
But I still don't have clear understanding of last 16 bytes (command payload)
