just checked the Dallas Maxim website, the MAX3421E is now on the
website.

looks the dogs bollocks ( an English expression denoting approval)
wish I could write the software for it, but I am just a hardware guy who plays with C

Nice. The pity is that it is Maxim, which often means appalling sourcing problems...

PC-side drivers are the biggest issue with the USB interface chips. As far as I know only Microchip and FTDI provide them. Logically, there should be 3-rd party companies that sell drivers for the USB chips, but I haven't seen any of them. If they don't exist, it makes sence to start one... |

| I think you have got the wrong end of the stick. This is a host controller, so the biggest issue is having a FAT compatible driver in the embedded design. |

It is both a peripheral and a host controller so it has both classes of challenges. It has no Virtual Comm port driver which is unfortunate, I was hoping to use this to replace the FTDI chip because of the high I/O cost associated with interfacing the FTDI chip but such is life.
Also this chip is not actually shipping yet
