Dell Monitor Usb Hub Not Working

• #one

I'm trying to diagnose a problem at one of my clients that has the micro form factor Optiplexes. They take Dell P-series 24" monitors, that have the 2 USB ports on the side of them. The monitors USB connection is "Type B". Does anyone know if the monitors supply their own ability to the USB ports?

I've got a situation where things volition work when plugged into the monitor, but not when plugged straight into the estimator. This is an auto shop - they have a barcode scanner and a laser printer (both currently plugged into the monitor - which allows them to work). Otherwise, at that place is just keyboard & mouse plugged into the reckoner (which also work). Plugging in a flash drive to whatever of the unoccupied USB ports on the figurer doesn't piece of work - no recognition tone and no drive showing up in explorer or disk manager - as if they are not continued.

The original symptom was that the printer stopped working - and I haven't been onsite yet, but just talked them through some things to try. These are pretty new units, only a couple of months erstwhile. I'one thousand wondering if those micro PCs take don't take enough juice, their power bricks are simply 65W. Both the laser printer and scanner wand are old, and so maybe something is at fault at that place likewise. For now, plugging them into the monitor USB ports made them work, but if in that location is a problem with the computer itself, I don't desire to wait before starting down that path. Something isn't right if the computer can't even detect a flash drive. We've got a couple of dozen of these microPCs out in the field - I hope this doesn't turn out to be one of their weaknesses...

Yes they are powered, there is a setting in the monitor menus to enable ability when the monitor is off.

Some are powered... not all are. (I'd dare say near, but I've run into a few that weren't)

Given what you're reporting I'd say it's fair to assume the Dell display you lot're working with is powered. And if that brandish's powered hub is sorting out admission, either the devices they're working with are incompatible with the desktop'due south USB bus, or they're as y'all assume... not putting out sufficient power to energize the device.

I've never had a printer not piece of work due to low USB power... because they have their own power. Nor have I ever had issues with USB keyboards and mice. BUT... I accept had plenty of issues with USB POS equipment, bar code scanners, light poles, etc. It got to a point where I started using powered USB hubs for all my POS installs just to ensure things worked. It also gives me a nice single place to "unplug" everything via an IP Power switch.

I've NEVER seen a Dell P series monitor that didn't provide power. YMMV on other brands or other Dell monitors but the P series is powered, it 1 of the selling points for the monitor.

That is a fair point, my comments weren't limited to Dell P-Series, as I missed that particular when I scanned the mail service. Instead I was thinking Dell monitors with USB.

Ok - thanks guys. Unfortunately, this is the front end desk-bound/checkout computer, and so there isn't much downtime to check things out. When information technology'southward not in use, they are closed and no one is there. When they are there, it is in use and can't be taken down - not exactly something that can be troubleshooted (troubleshot?) remotely, either. Ugh - I guess I'll have to ask them to open up on a Saturday for me to figure this out. Ugh.

Ok - cheers guys. Unfortunately, this is the front desk/checkout estimator, so in that location isn't much downtime to bank check things out. When it'southward not in use, they are closed and no one is there. When they are there, it is in employ and can't be taken down - not exactly something that tin can be troubleshooted (troubleshot?) remotely, either. Ugh - I guess I'll accept to inquire them to open up up on a Saturday for me to effigy this out. Ugh.

I can easily come across one of those mini'south not being able to power a scanner. What is incorrect with it plugged into the monitor? You'd accept to drop in a powered hub which is the same affair.

I can hands see ane of those mini'south not existence able to power a scanner. What is wrong with it plugged into the monitor? You'd have to drop in a powered hub which is the same thing.

Yep, zippo wrong with using the monitor hub - it's the dead ports on a new computer that is the concern - just have to deal with it, that's all. I hate stuff like this on a new install, not really a big deal, only unfortunate. Hopefully if it is hardware, it will be covered by Dell. We'll see. At least we made them become a UPS, then hopefully won't go blamed if it was a power affair. Plus - they're MY mechanic and very skillful then I don't desire to sully that relationship either!
