Brother printer/scanner: Get scanner working

Hi,
In another thread, I explained how to set the Linux client for a USB Brother DCP7055 printer. This is working fine now from 2 clients through my router with Openwrt/p910nd Printer Server.

Now I want to start and get scan from the same clients but I can't find the right backend file.
I followed this howto but when I have to choose the backend (driver) there is no Brother brand. As said in the howto, I tried all the provided backend but none is working.
Maybe this printer is not compatible and nobody succeeded to get the scanner working. I'd like to be sure.
Do you have a Brother DCP7055 or similar, scanner working with sane?
Any help is welcome.
Thank you

Thank you Alex,
As you may have notice, my scanner/printer in NOT in the sane list, so maybe it's not compatible.
The first link you provided is interesting, I'll have a look to see if and how I could modify the driver but I am afraid it's above my knowledge...
What I read is the scan driver (backend) uses spooling to get the scan, so I am wondering why it's not like the p910nd Printer Server, direct link from device to client, the driver only translate network to USB, both ways.

So I am still on the need of a working solution.

Hello there,
For some reason, the above post from danielniro is flagged and the user is banned until 3019. Maybe this is for a good reason but this is a pity; Due to personal circumstances, I ended up to still have the original issue, connecting the Brother printer/scanner to Openwrt.
The user seems to have solve this issue and I can't get any information from him about how he fixed it.
Is there a way to get the information?
Thanks

The post you mention is just SPAM, there is no info there about your issue.

I agree, there is no info in the post but the user said

He seems to have a solution and I'd like to ask to him.

You will not get any usable answer from a spammer, since his only motivation to post in forums is to spam. He certainly never had any of the problems mentioned in this topic.

Ok I understand. I didn't click the link, I suppose it was as you wrote.
Sorry for my ignorance.
Thanks

Hey, I know it's been a while but did you manage to setup your scanner?

I purchased an Archer C7 v5 router and a printer/scanner combo, a Brother DCP-1602 laser printer. I've flubbed around a bit trying to find a proper SANE driver for it or to configure SANE over the network but was unsucessful. I did manage to get it working over the lan with usbip and with the 17.01 libudev package using the command: "opkg install --force-downgrade libudev_3.2-1_mips_24kc.ipk", without quotes. There was no problem in the official Brothers linux scanners drivers installation and utilization with a linux machine but there's no official usbip support in windows!

The only available solution is the unofficial usbip for windows however it doesn't have an official driver certificate, requiring test signing to be turned on...

Did you find a more agreeable solution?

Thanks

Hi T4V0,
This is an old thread but is still in the agenda. I had not time to go further.
As I understand you found a way. Maybe the bug in libudev was the issue.
Thank you to let me know, I'll be back in few days to let you know if it's working.

Hi, just letting you know there's an alternative to usbip that works with windows, virtualhere usb server, its trial version only works with one device at a time but it's compiled to a few CPUs architecture (i386, AMD64, ARM, ARM64, MIPS and MIPSEL), I'll use it until there's a official usbip version for windows.

I don't know why this post was marked as spam, I just suggested an alternative to usbip on windows since there's no free one available, if there's another similar free program compatible with windows I would like to hear it. I searched other usb over the internet programs and this one is the only one that offered a trial version without a time limit, and I'm not being paid to suggest it, I wanted to use only usbip but, to reiterate, choosing between the uncertificated usbip-win, that requires windows to be in test mode, or a certificated program in trial version, I preffer the latter.

Hi T4V0,
As you are experienced in scanner install, could you advise about usbip package install, 6 are in the repo:
usbip
usbip-client
usbip-server
kmod-usbip
kmod-usbip-client
kmod-usbip-server
Which ones are necessary to run the scanner?
BTW, I run Linux Opensuse 15.2 on my desktop
Thanks

You need the usbip-server package for the router, it should automatically install the packages usbip, kmod-usbip and kmod-usbip-server since they are its dependencies. Don't forget you need to downgrade your libudev package with the older package built for your router's architecture, I recommend restarting the router after the installation.

And for your desktop, you need to install the official linux driver for your printer, in the Brother's driver website there's a .rpm package, which is the supported package type for your distro. You also might need to install a SANE frontend, I use simple-scan.

Hard time for me.
I tried to install the previous version of libudev

opkg update
opkg install --force-downgrade libudev_3.2-1_arm_cortex-a9_vfpv3.ipk
Collected errors:
 * wfopen: libudev_3.2-1_arm_cortex-a9_vfpv3.ipk: No such file or directory.
 * pkg_init_from_file: Failed to extract control file from libudev_3.2-1_arm_cortex-a9_vfpv3.ipk.

I removed the installed version

opkg remove --force-depends libudev-fbsd

and tried again but again same error.
I downloaded it and tried with the GUI

Executing package manager

Installing libudev-fbsd (20171216-1) to root...

Errors

Collected errors:

The opkg install command failed with code 255.

Any help?

Did you download the package and transfer it to your router?

From your desktop's terminal:

wget https://downloads.openwrt.org/releases/17.01.6/packages/arm_cortex-a9_vfpv3/packages/libudev_3.2-1_arm_cortex-a9_vfpv3.ipk

Then transferring to the router:

scp libudev_3.2-1_arm_cortex-a9_vfpv3.ipk root@openwrt:/root/

And then, after entering your router's shell:

opkg --force-depends remove libudev-fbsd

opkg --force-downgrade install libudev_3.2-1_arm_cortex-a9_vfpv3.ipk

And restart.

I did it with the command line from the repo, from GUI local (separately downloaded) and again following your commands. Same error!?

Can you paste here the error message?

And the output of the command:

opkg info libudev

I did a reboot, still the same

~# opkg info libudev
~# 

~# opkg --force-downgrade install libudev_3.2-1_arm_cortex-a9_vfpv3.ipk

opkg info libudev => No answer
libudev is not installed

Is

libudev-fbsd

installed might need to resolve conflict with that first.
