    Hello, yeap I have a bit. Pretty simple in fact. I need to take time to document it.
    If you have IDA and some knowledge in assembly, I have renamed all the functions in the driver dll :sparkles:
    Ok, I’ll try to send u something for Sunday
    I’m a bit busy for the moment but I’ll try to send u the most important things

    Hi everyone.
    Is this project moving forward? I see no activity on github, si I assume nothing is happening.
    Thanks for your help.

    Hey! Is there anything new? Or can I help in any way?

    Hey
    Hmm, I’ve heard that Goodix is working for a Linux driver. I’m still working on it in my spare time ( not a lot for the moment )
    If you have some knowledge in assembly, the windows dll file is in the git repository, I have also put a ida file with some functions renamed
    Ao2 has created a tool to dump some infos and put his ghidra file on it too

    Where did you hear that? From goodix officials ?

    any news on a driver please? it's not a show-stopper but it would be nice to be able to use the fingerprint reader on my Dell XPS15 2in1.

    @IDerr
    Hello, not the for the moment ao2 is still working in his repo, I should contact goodix to see if there’s something coming from their part. If not, I’ll get back to this next year

    Hi there
    just wanted to let you know, that the device id 27c6:5395 is also build into the Precision 5540. So, the XPS models are not alone anymore. ;-)

    @IDerr
    Hi thanks for that, I will build a list of all devices equipped with this reader !
    The thread where a developer from Goodix said
    we are developing linux-based drivers now.

    FYI Seems like brand new (2020) XPS 13 model got Fingerprint scanner under Ubuntu - https://www.phoronix.com/scan.php?page=news_item&px=Dell-XPS-13-DE-Icelake-2020

    Not sure what hardware is used there, but maybe it's also something what can also help with integration of scanner into older models...

    Hello :)
    Thanks for this, gonna look into it

    @IDerr
    Nothing available for the moment, on Dell's website
    Perhaps, not deployed yet...

    It looks like the Dell XPS 13 9300 has a proprietary driver now. Would it be possible to glean any information from this?
    https://wiki.archlinux.org/index.php/Dell_XPS_13_(9300)#Fingerprint_sensor
    It is a different FP reader model, though (27c6:532d)
    iderr
    @IDerr
    yeah, will need to check this, seems interesting
    and honestly, I think that 90% of the code will be nearly the same :D

    Hi! Any update on this? Though we're all quite busy this year.
    Would this provide any help in developing the missing driver(s)?

    I'd love to help with this as a hobby project but i have no experience with developing drivers and very little with reverse engineering; do tell me if there's something i could give you a hand with.

    Hi all
    I've been working on a driver for the SPI-based chip in my Huawei Matebook Pro X, and have been making reasonable progress
    As far as I know it's doing things similarly to the XPS-style readers, just with SPI instead of USB
    Does anyone here have hardware that works with Goodix's proprietary driver, and would be able to help me figure out how it operates?
    It contradicts my understanding of the Windows Hello security model, because it seems to let an unprivileged userspace binary get the PSK for communication with the device
    Jamie
    @JJJollyjim
    so it could be key to getting the TLS handshake and decryption working without the awful hacks I did to get the PSK from my chip

    I have this fingerprint chip in my Dell XPS15 with 8th gen i7. I could run up a windows VM and map the reader through to it, if that allows some kind of diagnostics or snooping on the bus?
