I created the following circuit. But when I connect the circuit with a Windows 7 system oder Windows XP system, Windows say unknown device. I created the circuit like the self-powered hub, individual port power management in the datasheet Figure 11. What is wrong in the circuit. I ask for help, please.
windows say error code 43
This device has been stopped because it has reported problems.
now the usb hub is detected, but not the usb device (usb flash)
I change the RESET (pin 4) from gnd to a RC circuit. 3,3V to 2,2k to 0,1uF and Reset pin. like here
also I've corrected my mistake. the 3,3V and 1,5k connected to D+ or DP0 and not to the DM0
also I change the resistors on the connectors by DP0, DM0, DP1 and DM1 to 27R
now only has to be the usb flash detected. the voltage on the USB flash (VBUS) is only 0,5V. maybe that's a clue. the led on the usb flash lights on short time.
error solved. pull-up resistor on the OVRCUR have missed.
why TI not write this in the datasheet from the tusb2046b and only in the datasheet from tps2044???
that is here the big question!?!?!?!
for comparison the figure from the tusb2046b datasheet
I'm glad you have fixed your problem and thank you for the recommendations.
