The shape of the uncontrolleddamage the device as well as the DS The shape of the uncontrolled falling edge is determined by the capacitance of the. But i can’t imagine that this usb-port which is capable of mA should have a problem with a few mA.

This is all very strange to me and i’m a bit helpless where to search the error. But this current peaks should be blocked by the capacitors in the usb power supply lines 33pF, nF, 4,7uF.

Thanks for posting it. The failure happens after a few successful transactions.

Usb problem with DS2490

I was impressed that everything seems to dds2490 very fine at first. Return to Other Products from Adafruit. If this is not sufficient i guess i would need a choke coil instead which is larger than the whole circuit itself: Yes that’s how i expected. As a 1-Wire master, the DS is not as.

Please be positive and constructive with your questions and comments. The peripheral function is a USB to 1.

In case a device has a failure, the usb driver can turn off the power for the specific port. No problems, does the trick. Your laptop however, may use such a switch — because a molt fuse is inconvenient in a laptop — and thus, cause problems. It may be a related issue, though. The DSR uses the D chip. The section of the DSR datasheet you quoted above says it “applies strong pullup to 5V”, and that would be parallel to the ones between the IO pins and the HV pin.

The DS supports a strong pullup and active pullup. Since this is your circuit, it would be hard to have prior reports.

OWFS Developers – Usb problem with DS

USB disconnect, address 4 usb Indeed I am totally new to electronics so I’m just trying to make sense of this as I go along: Additionally every other peripheral like webcams, cardreader, hdd work on the omnibook with or without the hub. Usb problem with DS And i would say that the ifs are electrically well designed. DS 0x 0x 0x04FA. What does the USB datzsheet say on that?

The 8-channel version of the DS makes it easy to split a larger application into smaller networks with fewer 1-Wire devices on each line. If the power supply would be switched the choke coils would make bad things too. Wouldn’t this be a chicken and egg problem? USB disconnect, address 3 usb But this makes no improvement which would surprised me. In reply to this post by Vortex-4 Am Montag, 4.
