kn1cht commented 6 years ago

@prasadjain05 Actually, I could not read data from USB drive through CH375. Getting status of USB device was successful, but getting descriptor failed with error.

Finally I gave up using this module and bought Arduino USB Host Shield.

@kn1cht thank you CAN YOU GIVE ME DETAILS ABOUT HEX YOU GET FROM THE CH375b WHEN SEND COMMAND SINCE I GOT REPLY FOR CMD= 0X22 WHICH IS 28ff AND IM UNABLE TO UNDERSTAND IT

kn1cht commented 6 years ago

@prasadjain05 Details of commands are in this datasheet (pp. 3-9). The list of reply for 0x22 is on p.9.

According to the datasheet, 0x28(00101000) is an error code and stands for "device return over time, no return."
