Original question:

TUSB4020BI: TUSB4020 Driver

TUSB4020BI: Windows 10 driver or utility to change VID/PID

Aare Tali1

Part Number: TUSB4020BI

We have a design based on TUSB4020. It is identified in Windows 10 as an 'unknown device' with VID 0451 PID 80FF. Windows Update does not have any drivers for this VID/PID combination. We have unprogrammed I2C EEPROM attached to the chip, so we can program it if necessary.

Where can I get the EEPROM programming utility? Which VID/PID should I use so that Windows would recognize the hub? Or, if PID 80FF is supported, where can I get the drivers?

Thanks,

Aare

    Hi Aare,

    TUSB4020BI uses the default USB drivers in both linux and windows. Please accept my friend request so that I can send you the software through E2E DM. Please post on your original thread once you have done so.

    Thanks, got the software. It works. The installer also contains driver for VID 0451 PID 80FF so that the hub chip with unprogrammed EEPROM is clearly identified as such. Writing 55 into location 00 disabled the programming, but with Arduino and I2C level shifter I could wire it up to the EEPROM directly while it was connected to the hub chip and write 00 into location 00 and program the EEPROM over and over.
