Hello! We use in our device TUSB2046BIRHBT. Used in conjunction with PCM-3362 with Windows 10. Crystal MQ-6.000-12-30 / 30/4085
We have a problem when using in conditions of low temperatures (-20 ℃). The chip does not start. In some cases, oscillator starts, and in some not.
Error occurs “Request for a USB device descriptor failed - code 43”.
We tried:
1) Changed the nominal values of the RC circuit (Reset): -Recommended 15kOhm + 1µF
-4.7 kOhm + 0.1 μF (delay 470 μs)
- 10kΩ + 1µF (10ms delay)
2) replaced the power bus (buspwr)
3) tried to run without downstream ports
4) tried to change a hub with tusb2046 to another usb hub device (made in China)
