stm32L452CEU6 usb doesnt work with Samsung GalaxyTab A8

anees
Associate II

I have a board design based on stm32L452 , USB gets recognized on a windows PC and I can talk to the device over any software like putty and a Test software sees the com port and can to the device. However in Android (Iam using samsung  GalaxyTab A8), usb is not even recognized. The Tab support OTG mode and I did change default USB mode in the tab (Tried all the combo, file transfer, teethering, media etc). Nothing helps. Any advice is greatly appreciated
