Dear Team,

My customer wants to use TUSB8020B on their Qualcomm based tablet project and they need Linux driver for this device. Do we have a driver for TUSB8020B?

Hello Caglar,

The TUSB8020B uses generic USB hub drivers. TI does not provide the hub drivers, they should be part of the standard Linux build.

Hi JMMN,

They need some assistance to find the related part on the Linux. Which driver integrated into Linux can drive thi part? They need to do GPIO configuration even it is integrated on Linux.
If it is not available on BSP, they need to get this from mainline linux kernel. Which module is related to this part?

Best Regards,

Caglar

Hi Caglar,

You can use the lsusb -t command to find out which driver is loaded for the hub. I believe it should be usb/core/hub.c or similar.

Hi JMMN,

My customer has a problem to make the circuit up and running on their board. they asked me to review their schematics to see if it is OK.

Could you please let me know how can I send the schematics to you? I cannot post it here.
