Hi
I am using beaglebone black with Linux am335x-evm 3.2.0 kernel. We have connected Edimax EW-7811Un Wireless Adapter [Realtek RTL8188CUS] to its USB port and it is working fine. But when we connect tusb2036 hub to the usb port and Edimax is connected to tusb2036 HUB, Edimax is not working properly.
We have checked the voltge in the hub and it is fine.We can connect and communicate to usb mass storage device and 3g huawei dongle which is connected to tsusb2036 hub.
Please let me know the issue and how can i resolve it.
