Agreed - I had overread this detail. > On my machine with an external hub I do get messages about power budget > being exceeded so it's probably not that. That's a design issue. Some ports implement overcurrent protection by self healing fuses. Others do not even that. I've seen many awfull cheap implementations. Btw.: I had seen similar problems with a self build device on some ports. It turned out to be a problem with the device oscillator to not properly work under some conditions. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
