As usual, when dealing with a microsoft product, one ends up doing free remote PC support for a paying beta product (paid to m$, not to me). I have problems with mcp2200 based devices which work on several versions of xp an= d w7 but not on some xp's. The lack of a net-accessible driver and the fact that it is only supplied as a zip file (no online driver for windows to find, no exe for user to install without hassle), is not helpful. I see that newer drivers (.exe for x64) exist. What do others do to fix/prevent this problem? Is it possible to place an online repository of relevant databases (.inf) and point windows at them somehow? By me, by others? I have no intention to play phone support guy for pc software I did not write, test, or am paid for. -- update -- Adding to what I wrote: There is an exe install now, under: http://ww1.microchip.com/downloads/en/DeviceDoc/MCP2200%20Windows%20Driver%= 202013-02-21.zip Okay, so maybe my problem is going to go away, I posted this to the person who needs it now. Anyway, the discussion remains valid. Is there a way to add a .inf or whatever repository online and 'tell' windows to go look there? Linux has been able to do this since ages immemorial. Oh, wait, linux is not for pay beta software, it is sort of freeish. There's my msitake comparing the two, I guess... -- note -- this was originally posted on another mailing list, by mistake. --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
