As Microsoft prepares to unleash Vista to all and sundry on the 30th January, it appears some manufacturers are still struggling to get their Vista drivers ready.

We've already come across two products that won't work with Vista - Lexmark's X2350 all-in-one printer (in fact, a number of Lexmark printers are in a similar situation) and HP's new G4050 scanner.

What's even more frustrating is that there's no indication of when these drivers are likely to be ready.

Lexmark has a release schedule for its Vista drivers, but many models are simply listed as "coming soon".

Meanwhile, HP's driver download site says " If what you were looking for is not listed, then it is not available for downloading from the web in this language", which isn't particularly helpful.

Hopefully all will be sorted by the end of the month, otherwise there could be a fair few disgruntled Vista owners who can't use their old XP peripherals.
