I was able to test the mainline 4.10-rc4 kernel with my RPI 2 and my
edimax wifi.  Basically it works, but it's flaky.  For some weird
reason I can ssh into the RPI 2 through the Wifi(Ethernet
disconnected).  But if I use the RPI 2 to ping certain addresses it
works and others it does work.  All the addresses are on the
same subnet.

Here are the USB devices that lsusb reports that I have attached:
Bus 001 Device 006: ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un
802.11n Wireless Adapter [Realtek RTL8188CUS]
Bus 001 Device 005: ID 093a:2510 Pixart Imaging, Inc. Optical Mouse
Bus 001 Device 004: ID 04d9:1702 Holtek Semiconductor, Inc. Keyboard
LKS02
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. SMC9514
Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I'm starting to think that maybe this isn't a USB issue at
all.  Perhaps it's more of a network issue. Like I said on this version
of the kernel, wired networking works but Wifi is flaky.
