I just got my LarkBox, and like so many, ended up having to reinstall Windows from scratch when their install bluescreened after running updates. Now I have a single bang in Device Manager, for “PCI Data Acquisition and Signal Processing Controller.” CHUWI really needs to make the necessary downloads available. Anyone know where I might find the driver I need to fix this bang?
Did you check what they posted on Indiegogo’s page? Maybe proper drivers are available in there…
(I’ve installed from scratch on a new SSD,so I was able to grab drivers from the old eMMC…
Yep, good call. Comments for the campaign include a link to a new installable system image, so I’m building that now and will give that a shot later. Thanks for the push.

You’re welcome,keep us informed if this ‘update’ is valuable 
Working a treat so far; I was able to get everything updated without it hanging on me, and the system as a whole seems to be running a lot cooler than it was last night, so if that was released to address fan issues, I’d say it succeeded…

Could you detail what you did with their image to get it on the SSD? Using it as they prescribe it just auto-installs on the eMMC. I’ve got a working install on my SSD, but Windows is stuck without drivers for the “PCI Data Acquisition and Signal Processing Controller”
If you still have your eMMC partition, then you can “Update driver” from Devices Manager and pick the drivers ‘locally’ from /Windows/System32. At least that’s what I did successfully
Yeah, I cant, because I wanted it on the eMMC. I prefer keeping the OS and apps separate from my own data.
I’m downloading that zip, basically it’s a modified windows 10 image with the drivers?
Btw how come there no trace of J4115 on intel’s website?
EDIT: I gave up downloading the zip, 13 hours download is a bit too much…
That should be the Intel Dynamic Thermal blah blah blah…
Here are the original Windows 10 drivers (eMMC version) extracted from Chuwi image for your reference.

@Management, can you please provide the link to the official OS builds as well as the official drivers for Larkbox and Larkbox Pro?
I already posted that any update to the Bluetooth drivers is causing a blue screen of death and that also the standard windows updates aren’t working for me, when will this be fixed?
I downloaded the Intel Driver and Support Assistant. It found all the drivers for me.
I returned my Larkbox Pro to the seller…
Really? No missing “PCI Data Acquisition and Signal Processing Controller.” in device manager anymore? That must have been a recent change then. Did it point you towards a download for chipset drivers?
I’ll check again to be sure but my Bluetooth and WiFi drivers all worked fine. I’ll check my PC again and let you know.
You were right, it fixed everything but that issue. I had to run the Intel Driver manager app twice to fix the Bluetooth and WIFI issues so I assumed that was fixed when everything worked the second time. The lack of this drive doesn’t seem to affect the functionality of my Lark box so far. Sorry for the goof!
