HP Slate 21 ADB Driver

I need to develop on the Slate 21 and have a hard time finding the right ADB driver for it - the generic one that comes does not work. I've tried a couple other solutions but cannot seem to find anything that works. Can someone point me in the right direction? I don't mind if its not officially supported.

Re: HP Slate 21 ADB Driver

Hi Sirry, could you please confirm what OS you are using.  I assume this is Windows, but want to be sure.

 

Also, just FYI, if you have access to a Linux box, you can use ADB without additional drivers.  Just put the system in developer mode, connect a USB A to USB A cable and you should be good to go.

 

Thanks,

Re: HP Slate 21 ADB Driver

Here are the "unoffical" steps to get driver support in Windows.  I tried in Windows 7 and it worked for me.  Please let me know your results.

 

  1. Download Google USB driver from here: http://developer.android.com/sdk/win-usb.html#top
  2. Once downloaded, unzip the package, there’s a usb_driver directory. Inside there open “android_winusb.inf” with notepad.
  3. Add the 3 lines below to the sections [Google.NTx86] and [Google.NTamd64]:

;slate21

%SingleAdbInterface%        = USB_Install, USB\VID_0955&PID_7100

%CompositeAdbInterface%     = USB_Install, USB\VID_0955&PID_7100&MI_01

 

4. In Device manager, select the Slate 21device and go to driver ->  update driver -> browser my computer for driver software, select the usb_driver directory you just edited.

 

Hope this helps,

Re: HP Slate 21 ADB Driver

Thanks for the help!

I actually got it to work another way I found online, by updating the driver through the device manager, and then selecting

browse my computer for driver software, then let me pick from a list of drivers, then clicking have disk, then pointing to the folder android users usually install the driver from and selecting the composite driver. 

 

I haven't done much with android since then, but I can vouch that a basic hello world program runs through adb.

Re: HP Slate 21 ADB Driver

Not sure if it's available under 4.2, but I think that the USB debugging got a wireless option (it's there on 4.3, just checked with other devices that I have).

 

COWA - is there a planned Android 4.3 or 4.4 update for Slate 21?

Re: HP Slate 21 ADB Driver

Hi Hetz,

 

On your first comment, yes there is wireless in 4.2.  I know a few folks have tried it successfully.  Not as straight forward as hooking up a cable but should be a solution if needed.

 

On the upgrade plans, I'm sorry but I can't comment on future plans/releases until they are formally announced through the proper channels.  Sorry I can't be more helpful, but I hope you understand.

 

Cheers,

Re: HP Slate 21 ADB Driver

Actually I just got my new Slate 21 and unfortunately, there is no Wifi Debugging option, also it reboots when you enable or disable USB debugging, which is weird...

[ Edited ]

Wifi debugging is possible, but you do need to connect with a cable first to enable it.

 

1) Enable developer mode on Slate 21 and turn on USB debugging (yes the unit will reboot)

2) Connect PC/Linux to Slate 21 using a USB A to USB A cable

3) In a terminal type "adb tcpip 5555" (you will see "restarting in TCP mode port: 5555")

4) Now you can use adb over wifi by typing "adb connect <your Slate 21 IP address>"

 

To re-enable ADB over USB type "adb USB"

Re: HP Slate 21 ADB Driver

Umm, why HP disabled the standard ADB over Wifi? it had a good security measure in it.

Re: HP Slate 21 ADB Driver

 

This isn't working for me. 

 

New ADT (22.3.0-887826) installed on Windows 7 USB A to USB A cable connected to Slate 21 on side port.

 

Slate 21 shows up in device manager as Portable Device. 

 

Debug sample project in ADT, no running Android devices listed. 

 

 

Downloaded Google USB Driver. 

 

Made edits to android_winusb.inf. 

 

Device Manager -> Portable Devices -> Slate 21 -> Update Driver Software -> Browse -> 

 

Selecting directory with inf file I get "The best driver software for your device is already installed." 

 

Selecting "Let me pick from a list of device" -> Have Disk -> select inf -> "the folder you specified doesn't contain a compatible software driver for you device"
