Part Number:TPS2541
We have a hardware design using the TPS2541. The CTRL pins are all pulled high. I am using a modified USB cable to connect from a port on my laptop to our hardware. Only the data pins from the USB cable are connected to my board.
I can plug USB thumb drives in and they work fine. But when I plug in an iPad, I get errors like this on the Linux host:
[445629.280650] usb 3-3: new high-speed USB device number 71 using xhci_hcd
[445629.400744] usb 3-3: Device not responding to setup address.
[445629.612731] usb 3-3: Device not responding to setup address.
[445629.820602] usb 3-3: device not accepting address 71, error -71
I'm not sure what could be going wrong here.
