Hello All, I use control transfer to read some bytes of data from a device. But I dont know how much data it is going to give me.
If I give less number of bytes as size, the usb_control_msg() function skips data (returns when the size number of bytes is read). If I give more number of bytes as size, the usb_control_msg() function returns timeout error. Is there any way to read n number of bytes from the device (using control transfer) when n is not known apriori ? Note: If I use usb_bulk_msg() with size = 1024, it always returns even if there is less number of data. Regards, Jayaprakash. ------------------------------------------------------- This SF.Net email is sponsored by the 'Do More With Dual!' webinar happening July 14 at 8am PDT/11am EDT.
