Does anyone have experience using multiport USB hubs on freebsd-arm, specifically in the context of Raspberry Pi 2 or 3? I'm interested in trying to use a hub/switch (not sure there's a difference in the case of USB) to construct a terminal server for serial console access on a small cluster of Pi's. I'd want about seven or eight ports, each holding a USB-serial adapter that would then connect to the GPIO UART pins on one Pi in the cluster. I've used both USB 3.0 and USB 1.1 hubs, and in both cases odd things seem to happen from time to time. One potential example is https://www.amazon.com/AmazonBasics-Port-USB-2-0-Hub/dp/B00GGYU46O/ref=sxin_2?keywords=powered+usb+hub&pd_rd_i=B00GGYU46O&pd_rd_r=83f1e3f0-a1e6-40aa-bdd8-aa86a7c0b360&pd_rd_w=foNmt&pd_rd_wg=ncKZR&pf_rd_p=0395a9fd-d124-46c0-a48f-d8582ed1a45c&pf_rd_r=2P9WWPAZGMAA29NMVVV2&qid=1552234319&s=gateway If anyone has experience along these lines or a suggestion for/against particular USB devices or versions I'd be curious to know. Thanks for reading, bob prohaska
