why do we not get the Descriptors like "Mobile AT Interface" ?

Thanks, Franz

Hi @diplfranzhoepfinger,

Strings descriptors as "Mobile AT Interface", "Mobile RNDIS Network Adapter", "Mobile Diag Interface" and others are the additional String Descriptors describing the Interfaces . These String Descriptors are not handled in the usb_host_lib example.

In usb_host library only the primary String Descriptors are requested from the device (which describes iManufacturer, iProduct, iSerialNumber), that is why these descriptors are absent in the output of the example.

Do you think that the feature to be able to get these descriptors via usb_host library will be useful?

I would love it.

@david-cermak would help in the esp-modem to get rid of these Descriptors:

having here , 4, 5)seems to be very bad style.

Thanks.
