Hackers, I'm currently testing my Bluetooth code for FreeBSD on recent -current. After i upgraded to recent current from current-DP1 i'm experiencing a major slowdown in USB device speed. On current-DP1 the USB device was able to handle about 50-60 KBytes/sec. On recent -current _the_same_ device driver can only do 11-12 KBytes/sec :( Another driver (PC-CARD) connected to my Bluetooth stack can do 50-60 KBytes/sec (sending/receiving) - so it is not a Bluetooth stack itself. Also the same USB device connected to Linux box can do 50-60 KBytes/sec - so it is not a USB device itself. The problem only exists when i connect USB device to -current FreeBSD box. I suspect that problem could be in: a) USB device driver b) USB stack itself c) someplace else? Does anyone have a similar problems? I'm slowly going though the diff's between DP1 USB code and -current USB code, but may be someone can give me a clue. thanks, max To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
