I have just upgraded from CC 15.05 RC3 to CC 15.05 Final on my HooToo TM-02. (openwrt-15.05-ramips-rt305x-ht-tm02-squashfs-sysupgrade.bin).  I have been using an EDIMax 7811u wireless USB adapter with the kmod-rtl8192cu package.

I have loaded up all the USB parts and this package, but the device is not recognized in Luci.  I have 2 adapters and they both work fine on PCs.   I see references to phy0 but not phy1, which is what I would expect the device to appear as.  I see this single line in the kernel logs, but nothing else that I can identify as relevant to the device.

[   22.430000] usbcore: registered new interface driver rtl8192cu

Looking for suggestions on how to trouble shoot and enable the device.

I have the following installed

Basic USB (installed, not sure that all are required)
kmod-scsi-core
kmod-usb-storage
kmod-crypto-hash
kmod-lib-crc16
block-mount

The required kmod-rtl8192cu installs all of the following:
kmod-rtl8192cu                 43kb
kmod-rtl8192c-common    18kb
kmod-rtlwifi                       28kb
kmod-rtlwifi-usb                8kb

The ticket below suggested the need for wpad.  I know I do not need both, but mini did not seem to help
https://dev.openwrt.org/ticket/17649
wpad-mini                     238KB
wpad                             395kb

It appears I neglected to install kmod-usb2.  Not sure it I need kmod-usb-ochi for USB data drives, but the wireless now works.

usb2 is sufficient.
ohci and/or uhci are for (older) usb 1.1 ports.

As I suspected.  I have got the USB thumb drive working with just the kmod-usb2
