USB Shakiness ---- OR a lack of CPU power?
USB Shakiness ---- OR a lack of CPU power?

Greetings,

I was reading all of the posts on the USB Shakiness issue, but got curious so I went and bought a DLink USB adapter. So, I have a Citrix / Win2K server and decided to give it a go. Well, it stayed up for several days straight. It also worked great for downloading over broadband internet, etc...

So, feeling Cocky, I decided I would try to Copy Win2K SP1 local to my HD from my LAN. Well, to put it mildly, it did not like it after about 20 MB. It would download over the internet connection fine, so it is nothing to do with the raw amount of data.

So, I am running Win ME, and I decided to poke around at my USB controller, and there is a page in there I have NEVER seen on another system before (probably never looked is why). It says that the USB port is maxed out at 11% of CPU time. Knowing how USB works, I have the following hypotheses:

1. USB Shakiness is not caused by lack of power (hence why external power makes no difference).
2. USB takes CPU power, and under low usage like Citrix, causes no disconnect. BUT under high usage like at large file, it can cause the CPU to interrupt the USB trasmission.

Thoughts?

Anyone know how to raise the 11% to lik 50%?

I found this same setting a while back but couldn't figure out how to change it either. It's probalby a registry setting.

Meanwhile, after trying just about every configuration possible, I went back to running WinME on a hard drive and now I have NO PROBLEMS AT ALL. My USB works perfectly. I was streaming mp3s from my desktop pc thru Winamp last night it kept playing and playing. It never cut out. I don't know why it suddenly works but I'm not about to mess with it again. Maybe a little leprechaun came in and fixed it in the middle of the night on St. Paddy's Day??????

I also got the power switch working according to the details in a recent posting.

One suggestion: Check the network card on your pc. I was using a crappy Netgear card and it just refused to work correcty with the WP. Now I use a good 3-Com NIC card and all is well. I run TCP/IP with internet connection sharing.


Cheers,

I am running 98se and have had no USB problems other than having to wait for network connections to start on power-up using my Linksys adapter. Once it is up it stays up.
I did change the bios setting for usb to legacy setting for dos(or somting like that). This seemed to help. Did you change it too?

Yes I enabled it in the bios. I kept playing with the settings.
I was having problems once in a while with re-booting. The USB would crash, I'd reboot, plug in the adapter and Windoze would hang. Then I'd repeat the process until the adapter worked.

With the USB Legacy enabled in the BIOS and the standby mode working, I no longer have to deal with the reboot mess.

Thanks again,
aadam12

I'm still having trouble with my SMC USB ethernet adapter.. After changing the BIOS setting to enable legacy support, it is a bit better but everything crashes after a period of time still and rebooting doesnt always help. Anyone have any luck with other settings in windows or the bios or finding new drivers?? I'm really hoping the USB issues can be resolved soon.
