Hi Anish and any one ese who found this page via google etc.
I can not find any drivers.
I've had a look, and once again I am left with a strong conviction the Edisonsoft 620 is the MA-620. Mobil Action will not support any of the cross branded products however. (Cross branding is when a company puts its own name on a product even though it was made by another company) I can't translate any of the asian languages(within websites and forums), but I can gather enough to reasure me, that is the situation.
Any suitable driver suites on the net, would be breaking copyright of Mobil Action (they go to great lengths to make you well aware of this), which is why I guess you don't see any drivers in other websites.
As stated above I believe in "maketh the product, suppith the driver -- and the webpage to deliver it" This is because the cost of supply and setting up a download site is cheap for a company to do, or at least let others share the burden. Any excuses, not to suppy a driver, involving fears another company might re-engineer said software, is bogus.
NOT many long term companies, market computer products worldwide without a decent download and support site. ie "Good" companies have have a "easy to find" legacy support download section. I stick to and recommend companies that have "stayin power" and have yet to let me down in a major fashion.
SO HEAR IS MY WARNING:: Avoid the purchase of any ir-usb product, that you can not confirm with vendor, has a LONGTERM support website with drivers FREELY AVAILABLE to the GLOBAL commmunity.
eg. if you see Edisonsoft, bafo, Mobile Action in the advertising material in a IR-usb adapter product advertisement, which none have freely available drivers, I would not recommend them.
If you have bought such a product second hand, there is no point searching for, say MA620driver.zip (250k) as most of file searching via web has been neutered. So has google for the same reasons. [Yep in what I do, books/libraries are again out doing the WWW, which once held such great hopes - ah well...So much for the electronic information age, which has succumbed to same fears which though out history, has lead to books and manuscripts being burnt and destroyed .]
