Part Number: TUSB4041I

Hi Team,

My customer is looking for the TUSB4041I Windows 10 Driver. He told me that Win10 could not get it automatically when he uses the device TUSB4041I.

Regards,

Hello Renan,

You do not need need a specific driver for TUSB4041. It should work when plugged into a windows 10 machine. It may be an issue with your circuit or with your generic USB hub driver in windows.

Best,
Gerasimos

Hi! I am that customer.
Here is the schematic.
Is it possible that 1uF cap on GRSTz is not enough if I apply 3.3V and 1.1V simultaniously?

My bad, first comes 3.3V, then after 600ms 1.1V.

Shorting GRSTz cap wit tweezers has no effect.

Removing the resistor from smbus clk (R74) gave an effect: now I see 2 downstream usb ports.
It is working correctly now.
