I purchased a couple of USB-serial adapters. Unfortunately, given the lack of detail in the descriptions, they turned out to be
uchcom0: QinHeng Electronics (0x1a86) USB2.0-Ser! (0x7523), rev 1.10/2.54 According to https://nxr.netbsd.org/xref/src/sys/dev/usb/uchcom.c#40 this is "the worst USB-serial chip in the world." Do these work at all? (Get "tip: link down", then change to a uplcom0: Prolific Technology Inc. and all is well.) Cheers, Patrick
