External USB doesn't work

Hello guys, I'm having troubles with a external USB for keyboard, Bluetooth or whatever.
I soldered to 5V and GND on PB1000C, and D+, D- to usb Hub from Helders AIO, I tried on 2 usb and doesn't work. When I turn on the system, the pen drive or gamepad is power on but only few secs. I tried to solder on a 5V and GND directly on Power Strip and the same results. Tried with a fresh install of retropie and still not working. But if I remove the SD card from RP0 the gamepad still power on connected to external usb. What can I do? I need connect a keyboard to configure retropie and put in emulators.
I attach a few pictures (I followed the 3.0v schematic)

Go to the Lounge subforum. There is a thread there with support for my boards. Basically you'll need to set retropie to Usb 1.1 speeds to make it work.

Also check your wiring especially on the pizero usb pads.

Ey @Helder, how can edit the config.txt w/o keyboard? I can modify mounting SD card on PC?


Ok, I edited the config.txt and cmdline.txt but the issue persist. I double checked the solders and apparently correct.
May I need plug a Lipo Battery to power all the components? I'm testing only with the power supply connected to micro usb.

Thx
