@pali it can be very possible, even OTG mode but this depend on vbus switching and the patch will be very specialized pointing only for rx51 sensing speed of device can be done without a timer for bq24500. 32s is enough for all jobs now it is clear for me how to do this. as my post above.. first part ->hardware detection of the device power the vbus and read debug register here we have 3 cases 0 no device 1 low speed device 2 high or full after this, speed can be set and read device descriptor if the device is high speed then switch high speed devices can be read in full speed mode the goal of my script is to prove the concept @everybody [Announce] The n900 hostmode script unzip the attachment in a folder as root run Code: chmod 755 install.sh install.sh
