Problems while using ch341a programmer.

So I'm trying to flash a coreboot img to WINBOND W25Q128BV chip using my main desktop machine with an arch linux installation on it.
lsusb detects my programmer normally but when I'm trying to read data from the chip I get:

cb_out: error: LIBUSB_TRANSFER_TIMED_OUT
ch341a_spi_send_command: Failed to write 67683 bytes

cb_out: error: LIBUSB_TRANSFER_TIMED_OUT
enable_pins: Failed to write 9 bytes
Could not disable output pins.

Then follows:

cb_out: error: LIBUSB_TRANSFER_TIMED_OUT
config_stream: Failed to write 3 bytes
Could not configure stream interface.

lsusb output before I attempt reading from my bios chip:

Things I tried:

• Using IMSProg instead of flashrom.

• Reinstalling libusb.

• Installing driver for my programmer instead of using the stock kernel one.

Any help would be much appreciated! Thanks!

Re: Problems while using ch341a programmer.

1. What kernels did you tried (maybe try linux-lts)?
2. What usb ports did you tried: 1.0, 2.0, 3.0 or higher standard?
3. Unplug not needed things from usb ports and try again.
4. You may try this, but if 'use_both_schemes=y' will not work then try 'use_both_schemes=1'.

Edit:
Looks like 'use_both_schemes' is already set on arch standard linux kernel:

cat /sys/module/usbcore/parameters/use_both_schemes 
Y

1. I am on linux-lts kernel.
2. I've tried all ports available on my computer but unfortunately to no avail, I have usb ports 2.0 and 3.0.
3. I have only my mouse, keyboard and headphones plugged in but I will make an attempt without my headphones.
4. Use both schemes is set to true.
Thanks for the reply!

Re: Problems while using ch341a programmer.

Any news on this?
I'm getting the same errors.
I even tried another distro, but nothing changed.
