Stubborn Broadcom USH device on a Dell E6400

I recently revisited the driver installation on a Dell E6400 laptop.  There was one stubborn driver that I couldn't get working, the "Broadcom USH" device.  Dell's support website didn't list a driver for this so I went out on a wider search across the internet forum.  I found a lot of posts talking about installing the Control Vault device drivers.  So I grabbed the Dell ControlPoint Security Device Driver and found that it was useless.  The drivers were wrapped in an installer (that I didn't want to run, I just wanted the drivers).  Then I scrolled a little further down the page and found the Dell ControlVault Driver package (here's the page where I found it). After extracting that exe file I was left with a bunch of MST files and one MSI file.  So I extracted the MSI and there they were, the elusive drivers.  But it wasn't just a straight forward install.

I tried to install the driver, but it didn't work either.  It told me it couldn't find one of the files.  At first glance, everything was there.  So I ran DPInst against it.  It errored on two different drivers.  I looked through their INF files and found that they were looking for 2 files that weren't there.  A ccidflt.sys and a cvusbdrv.sys were missing.  Looking in the folder there was a ccidflt.sys2 and a cvusbdrv.sys1.  Close enough, right?   I removed the extra number from the ends of the extension and ran DPInst again and it worked!

So there you go, sometimes drivers can be stubborn.  But a little persistence pays off in the end.

Chromebook Chargers (HP, Samsung, and Dell)

Again with the Chromebook posts, right?  There are tons of reviews out there.  But you can only rehash the same specs so many times.  In the K-12 market I need to know about the physical properties of the devices too.  Let's face it, these things are going to take some abuse.  What takes more abuse than the power connector?  The charger is going to be plugged up every day, it's got to be tough.

My first experience with a Chromebook was the Samsung Chromebook.  No model number, just the Chromebook.  That was the first ARM based one that was priced at $249.  My thoughts initial thoughts were wow, it's light, it's thin, maybe a little flimsy, but what's with that crazy small charger connector.  Really, is this a Nokia phone from 2008?  In saying that, I still love that particular model.  I was just worried about unleashing a hoard of students on that small connector.  The teachers haven't had an issue with it, but I feared the students.  I've seen what they were capable of with much more robust connectors.

Then I came across the HP Chromebook 11.  Not as thin or light, but not as flimsy either.  So how did that charger connector stack up?  It's micro-usb.  That's great, right?  I really thought it was.  It's micro-usb! Most of these kids are used to plugging these up with their cell phones.  My toddler can plug up a micro-usb connector.  Not to mention that micro-usb chargers are everywhere which should have been a huge advantage (but it's not, just Google it for the details, the short version is that cell charger doesn't provide enough juice, Chromebook battery will die while trying use and charge at same time).

All micro usb connectors are not the same.  The HP Chromebook 11 appears to have a micro-a usb socket.  What is that you ask?  It's almost just like the ubiquitous micro-usb connector.  In fact, the micro-b usb connector that you're used to works in a micro-a socket.  The big difference is that that micro-a connector is a rectangle, it doesn't have the "clipped" corners that make the micro-b connector look kind of like a trapezoid.  Here's a link to the USB Wikipedia article, they cover it better than I do and they have pictures, too.

What does the different connector mean to you? It means the socket doesn't have an obvious up side (or downside).  I know I'm guilty of blindly trying to plug a cable in, doesn't fit, flip it and try it again.  With the more common micro-b connector this isn't a problem.  The metal casing on the connector will only fit one way so if it doesn't fit, it just doesn't fit.  But the HP Chromebook 11 doesn't have a micro-b socket, it's got a micro-a socket.  This means that the metal casing will fit either way.  The only thing stopping it from going in upside down is the thin little plastic strip that holds the metal contacts.  Do you see the problem with this?

So enough about the Chromebook 11, how about the Chromebook 14?  It doesn't have the same problem as the 11.  It's got a more standard barrel connector.  It seems fairly robust.  I haven't spent much time with this one so I don't have a lot more to say about it.

Now let's get to the latest Chromebook that I've tried out.  The Dell Chromebook 11. I got it out of the box and was thrilled to see the standard Dell barrel connector.  The power adapter is a 65W adapter.  It's got rounded corners and doesn't look like the other Dell power bricks that I'm familiar with, but the business end is the same.  It even has the light up ring where the cord goes into the back side of the barrel connector.  I checked it out, it looked pretty cool.  But I didn't plug it up.  Right there on my desk was another Dell power adapter from another Dell laptop (not a Chromebook), I picked it up, plugged it in and.... It blew up.  Wait, no it didn't.  It just worked.

So there we go, the Dell Chromebook 11 has a nice big, fat, rugged power connector.  And it's not unique, it's a Dell connector.   There's a thriving market for Dell laptop chargers.  Try finding an after market HP Chromebook 11 charger (which isn't the same as a HP Chromebook 14).  Heck, try to find an OEM adapter for that matter.  The HP is always out of stock.  Good luck finding a replacement if your dog eats homework, er.... Chromebook charger.

A New Chromebox from Dell?

I swear this blog isn't just about Chrome devices, there's just been so much news about them lately and they're such a good fit for education.

It looks like Dell may be preparing to release a Chromebox.  They may have gotten to the Chromebook party really late but it looks like they might show up at the Chromebox party pretty close to everyone else.  Well, I guess technically Samsung has had a Chromebox out for years, but one person doesn't make a party.  They were just really early, because it seems like the Chromebox party is just starting.

I haven't seen any direct press from Dell about a standalone Chromebox, but I've seen Dell mentioned several times as being one of the providers of the Chromebox for Meetings* hardware.  In fact, here is Dell's own press release where they mention that they are developing a Dell Chromebox for meetings.  Surely if they're developing one for meetings they'll develop one that's not just for meetings.... You know, one that's good for regular day to day use, too.

If you happen to be stuck in a Dell only shop, it looks like you will not be left high and dry when it comes to Chromeboxes.

It looks like the Chromebox vendors are started to really line up.   It seems like Samsung has had one forever (they're on their 2nd generation) and now HP, Asus, and Dell are going to be releasing models.


*Just in case you missed the "Chromebox for Meetings" news, I'm not kidding, they really chose to call it Chromebox for Meetings, here's a link to the Google page to prove it:
