Hi, I was looking for some low-cost FGPA board for a home project. What I need it to have is
-USB 2.0
-Analog output/input (either)
-optionally several switches, leds, maybe display, but not necessary if has nice software control
-possibly pins to access FPGA ports directly, like a 40 or 50 pin connector
What I've found so far is
Hi, protel demo board ?

What is your board going to do? We have a new DSP (SHARC ADSP-2126x) and Altera Cyclone module and board coming out very soon. It is designed for embedded applications. Details will be on our web site in the next few weeks.
this one looks like what I've been looking for a while (a bigger FPGA would be better but what can i do ? ;o) However, anyone knows whats the status of the USBhigh-speed drivers for Linux ? XEM3001's apparently using Cypress CY68013 FX2 - is it supported under Linux ?

That would depend on how you program it. Class drivers for all the major types of devices exist, so if you program the FX2 to look like a serial port, or a hard drive, and you properly set the class ID in [r]enumeration, it'll just work.
If you program it differently, there's libusb which allows you to write "drivers" in user space, built into your app. libusb lets you fiddle with the low-level USB communications straight from your app, elimininating the need for a kernel-mode driver, but restricting operation to your application (or library, if you write your "driver" as one).
I haven't played with the FX2 personally yet, my devel board hasn't arrived from Bulgaria(!)
The interesting thing about the FX2 in conjunction with an FPGA is its AUTO mode, which is used by
TTYL, Omega aka Erik Walthinsen

An alpha release of the Linux API and drivers (they rely on libusb
has been released for Fedora Core 3 and SuSE 9.2, though they shoul work on distributions with similar gcc / library setups
The release includes the C++, Python, and Java APIs
