It won't have any effect on CONFIG_USB_BANDWIDTH, as the EHCI transaction translator scheudling code doesn't care about that config setting. This also won't have any effect on USB 2.0 devices (e.g. a highspeed Audio device). The updates will only help in the situation where there are multiple lowpseed or fullspeed devices with periodic endpoints, all connected to the same USB 2.0 (highspeed) hub. In that situation it's possible to "fill up" the USB 2.0 hub's transaction translator periodic schedule with only a few devices. The updates allow many more devices to fit in the TT's periodic schedule. The specific number of devices depends on how many periodic endpoints, those endpoint's poll rates, and their max packet sizes. -- Dan Streetman [EMAIL PROTECTED] --------------------- 186,272 miles per second: It isn't just a good idea, it's the law! ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
