Hi Guys,
Please help.USB_HUB.pdf
Our USB2512 HUB connected to USB0 is not getting detected. We are a little stuck and need to complete this spin to get to testing ASAP.
Please see attached schematics.
USB0_ID is pulled directly to gound - not shown on the attached sheet.
The USB0 mode in the kernel is set to MUSB_OTG.
USB0_VBUS is pulled to 5V with 1K.
We verified the input clk is 24MHz - we are not using a crystal.
Out put from cat /proc/driver/musb_hdrc.0 (I'm not sure what it must be?):
Status: MHDRC, Mode=Peripheral (Power=e0, DevCtl=19)
OTG state: b_idle; active

Peripheral address: 00

Gadget driver: android_usb
ep0 (hw0): 1buf, csr 0000 maxp 0000
