Almost no commercially available USB-RS422 adapter will work between a PC and the EII, because most of them don't support synchronous mode (external clocking).
That's why the EmuComBox was designed specifically for use between a PC (e.g. running EMXP) and the EII/Emax. This device supports the specifications required by Emu samplers.
Since - until now - the EmuComBox must be built by yourself, it depends how you actually construct it whether you can also use the cable provided by EmulatorArchive.
The EmuComBox should have a miniDIN8 connector installed (not mentioned in the construction manual) in order to re-use that specific cable.
However, the next version of the EmuComBox - called E-muSer (pronounced almost like Amuser :-) - will have a much more detailed construction manual and this device will use a DB9 connector instead of a direct wiring to the EII or instead of a miniDIN8 connector.
Pictures of the E-MuSer can already be found on the website:
http://www.emxp.net/EMUCOMBOX.htmWithin a month or so, I'll probably be able to ship some of these E-muSer devices to anyone who wants to buy and (still) test them.
Anyway, if you would succeed in getting or creating this small EmuComBox or EmuSer device, the latest version of EMXP is indeed able to transfer banks between a PC and the EII without any need for a Mac. Full bank transfers take about 20 seconds of transfer time as opposed to 13 seconds on a Mac.
As you suggest yourself, the Mac - EII connection is of course another good alternative. If you just want to use the CDR as a kind of hard disk via a computer for your EII, the Mac solution for sure is sufficient for you and will work. Be sure to buy a Mac Classic, Mac Powerbook 160-180 or Mac SE/HD, Mac SE/30...
The EMXP solution is an alternative if you don't want to go for an ancient Mac anymore. Or if you also want to use the other features of EMXP (which is indeed mainly focused on translations in case of an EII).
One last note: I know some people are quite impatient to get answers as soon as possible on the forums/groups. But I think saying that "relying on this forum you would be screwed" is quite an exageration. Be aware that you posted your question only one day ago, and that not all members even had the chance to post a reply.
Also, having members such as Dr.C on this group prooves that this forum has actually been helping many Emu-users in the recent past. Don't take all reactions too seriously, e.g. Elmbeatz is really a valuable member of this group... Moreover, the answer to your question could indeed also be found on the EMXP website (emucombox link) and in the manual of EMXP v2.09. But I'm aware that it's a lot to read or browse to find the very particular answer to your question...
