From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Vortex Sent: Monday, June 04, 2007 9:43 AM To: owfs-developers@lists.sourceforge.net Subject: Re: [Owfs-developers] Usb problem with DS2490 OP? Does that mean it's a known issue? But i can't imagine that this usb-port which is capable of 500mA should have a problem with a few mA. Spikes and something like that on the power lines should be sufficiently blocked by Capacitors and RF-Chokes which i already placed there. And due to your recommends i increased the Capacitors now. Without any improvement.
-------- I think "OP" is you. Since this is your circuit, it would be hard to have prior reports. OWFS certainly doesn't know or care about hubs -- it just uses libusb to enumerate USB devices and libusb for all communication. I realize your circuit only uses a few mA, but perhaps you are supplying a larger current to the 1-wire bus (which you are powering) than you realize?
