You could try pluggin it into other USB ports, some people have found that
they have to plug and unplug it a few times before it works... You might
have to buy new USB memory sticks which are fast enough to meet the specs.
As of right now, I do not know of anyone composing a complete list.
I am using the PNY Attache 4GB. I have read the Sandisk Cruzers also
work.There are a few others here who have given brand names of ones that
work. Just search for ReadyBoost.
Here is what speeds are required:
Q: What perf do you need on your device?
A: 2.5MB/sec throughput for 4K random reads and 1.75MB/sec throughput for
512K random writes
Q: My device says 12MB/sec (or 133x or something else) on the package but
windows says that it isn't fast enough to use as a ReadyBoost device... why?
A: Two possible reasons:
The numbers measure sequential performance and we measure random. We've seen
devices that have great sequential perf, but horrible random
The performance isn't consistantly fast across the entire device. Some
devices have 128M of lightning fast flash and the rest of the device is
really slow. This is fine for some applications but not ReadyBoost.
