Really interesting Ian, but the real question is how do you separate the real Prolific and FTDI chips from the fake. The fake Prolific chips have been on the market for a long time and would not work on Win 7. The only way I could find to avoid buying the fake chips was to avoid Prolific altogether. Now, you tell us (and others) that fake FTDI. I just spent 20 minutes on the HP web site trying to find out how long ago I bought my HP P6230 desk top and my Office Pro 6500 printer. I think that HP must have subbed their help site to the Chinese company that makes the fake chips.
We need to publish the names of the criminals that are repackaging and selling the fake chips. The best way I have found is to assume they are all fake or mixed fake and genuine and to avoid buying any and all products that do not advertise and supply genuine Prolific or FTDI chips. Since I do not know any manufacturers or sources that guarantee this and I have owned my computer since Win 7 was released, at the moment I still only know one method, avoid USB converters all together except for products furnished with a converter. Can you shed any light on this ubiquitous problem?

Like Prolific (the real Prolific company, that is) FTDI have updated their drivers to detect these fakes... but that also means that anyone who has bought a fake chip will have a non-working adapter. The message is always the same: fakes are hard to spot, so buy only from reliable distributors. FYI, the real FTDI company is a family-owned firm right here in Scotland's 'Silicon Glen'. 73 from Ian GM3SEK ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to wrco...@yahoo.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
