I have 15 Raspberry Pi’s. I’ve used the original B thru Pi 3, and the “zero".
I’ve had no issues with USB. I use Gentoo on all my Pi’s. I use USB for
bluetooth, WiFi & as the root partition (USB storage). I’ve used at least 5 x
brands of USB WiFi adapters. I’ve pretty much standardized on “Edimax
Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]” as
of late, but I’ve used other chip sets (from Amazon for < $10). I’ve never had
any WiFi issues or USB issues.
With regards to WiFi, if I ping a Pi, sometimes 1-3 pings fail, before the WiFi
seems to "wake up". I’ve not been able to track this down to a chipset or USB
specific (it happens on the Pi 3, with built-in Broadcom WiFi). All my scripts
that automate things with my Pi’s that are on WiFi, start with a “ping -c 4 -q
$host”. ALWAYS by the 4th ping, the Pi is responding. With the Ethernet,
always by the 2nd ping, the Pi is responding.
