Hi, Sorry if this is off topic for this list, but I don't know where else to=20 look.. I'm using SDCC to write a very simple polled communication for the EZ2131= =20 chip, with the usblib API on the linux host side, fxload for programming.= =20 I've got some problems with data returning out of order... like a read ge= ts=20 the previous packet I tried to read. Are there any good examples for sim= ple=20 polled IO beyond what's in the Cypress book. Another problem I've got is that sometimes the chip will disappear from t= he=20 USB system, and not respond to plugging/unplugging.. It comes up temporar= ily=20 as an unknown device with no endpoints then disapears again. I have to=20 completely restart my system to fix this. Is there a way I can just requ= est=20 the entire USB bus to reset? Thanks, Alex --=20 Alex Faveluke --...@dn... Systems Design Engineer Dynalink 503.682.9008 |
