Enabling developer features on the Fujitsu Arrows Tab (wifi-only edition)

Earlier today, I mistakenly announced that Fujitsu didn't include support for developers (e.g., adb and ddms) on the Arrows Tab. Fortunately, I was wrong. Big thanks goes to some of the guys hanging out on Google +, like Nikolay Elenkov and Jan Moren. I've now got full debugging going in a windows VM and on Mac OS 10.

Fujitsu is apparently well aware that there are potential issues because they include explicit instructions on how to fix it in a garbled mojibake text file that couldn't be displayed with any character encoding. (Viewing the readme (txt) directly in a browser with Shift_JIS works, and I've also pasted in the text, in UTF-8, at the bottom of this post.)

The problem was with the USB vendor ID, and the fix was the same as described here for the Sony S tablet. According to the Android developer site, this is what is required for setting up your environment to detect your device (emphasis mine):
  • If you're developing on Windows, you need to install a USB driver for adb. For an installation guide and links to OEM drivers, see the OEM USB Drivers document.
  • If you're developing on Mac OS X, it just works. Skip this step.
  • If you're developing on Ubuntu Linux, you need to add a udev rules file that contains a USB configuration for each type of device you want to use for development. In the rules file, each device manufacturer is identified by a unique vendor ID, as specified by the ATTR{idVendor} property. For a list of vendor IDs, see USB Vendor IDs, below...

Mac OS 10

No, it didn't just work on mac, though I've never had this problem with any of the tons of handsets I've connected to any mac. This is the first time. Ever. For any USB device.

Create an adb_usb.ini file at ~/.android, and add one, single entry: 0x04C5. This doesn't effect the ability to use adb or ddms with other handsets. This worked for me in Mac OS 10.6.7.


This should be straight forward, so follow the official directions at the Android developer site.


Here's how I got it working in on Windows XP in virtual box, which was quite a chore for me because I rarely use Windows.

Step 1. Create a filter to pass the USB from the host OS through to the guest OS (only needed for virtual machines.

Step 2. Download the USB drivers from here. Click agree to download (同意する).

Step 3. Unzip the driver to a convenient location.

Step 4. On the Arrows Tab, go to Settings/Applications/Developer and select enable USB debugging (USB デバッグ) and tap OK. [NOTE: language options on this tablet are English and Japanese.]

This screenshot wouldn't exist without ddms.
Step 5. Plug the Tablet into your PC, wait, and then do the standard rigamarole: don't let the Found New hardware wizard search the internet. Instead, point it to the location of the unzipped folder and install.

Installing USB drivers is sooo 1990s. Sigh.
The documentation from Fujitsu talks about a "Fujitsu HSUSB Device," bit displayed for me was "Android Composite ADB Interface."

Step 6. Next, run adb-update to add the Fujitsu's USB vendor ID (04C5) to your user account's adb_usb.ini file. From a dos prompt run the following (If the proper SDK folders aren't added to your path, you'll need to change to the proper directory):

android update adb

Step 7. Manually add the Fujitsu vendor ID. Go to C:\Documents and Settings\YourLoginName\.android and open adb_usb.ini with notepad or any text editor. The top of the file will say something about never, ever manually editing this file. Manually edit the file and add the following line:


And save the file. Then stop adb for good measure, and check to see if you device is recognized.

adb kill-server
adb devices

You should see the following:

* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached

Where xxxxxxx is your device. Now adb and ddms should work. Happy developing!
