Hi,

I tried to reach out to Brother support but they seem to use some kind of retarded AI/LLM which takes about a week to answer each time and then dont really provide any true solution.

First they recommended to install the iScan & Print app to perform firmware update throug smartphone.

When I pointed out that sure printing and scanning works that way but not firmware updates they then recommended to install the Mobile Connect app.

But they forgot to inform that when you try to add the MFC-9970CDW to the Mobile Connect app you get redirected to the iScan & Print app which again doesnt support firmware updates.

So question is how do I firmware update a Brother MFC-9970CDW and what is a trustful source to download latest firmware update for this model?

There are no firmware updates available over at:

https://www.brother.se/support/mfc9970cdw/downloads

According to support version P (released in 2014-09-11) is the latest available.

Does Kingston DC2000B M.2 2280 NVMe storage supports ASPM and what are the defined powerstates?

That is output of:

1. The parts with the drives:

   lspci -vv | awk '/ASPM/{print $0}' RS= | grep --color -P '(^[a-z0-9:.]+|ASPM )'

Along with:

2. The part of "Supported Power States":

   smartctl -a /dev/nvme0

For example here are the output for Micron 7450 MAX 800GB M.2 2280 NVMe drives:

01:00.0 Non-Volatile memory controller: Micron Technology Inc 7450 MAX NVMe SSD (rev 01) (prog-if 02 [NVM Express])
            LnkCap:	Port #0, Speed 16GT/s, Width x4, ASPM L0s L1, Exit Latency L0s <256ns, L1 unlimited
            LnkCtl:	ASPM Disabled; RCB 64 bytes, LnkDisable- CommClk+

06:00.0 Non-Volatile memory controller: Micron Technology Inc 7450 MAX NVMe SSD (rev 01) (prog-if 02 [NVM Express])
            LnkCap:	Port #0, Speed 16GT/s, Width x4, ASPM L0s L1, Exit Latency L0s <256ns, L1 unlimited
            LnkCtl:	ASPM Disabled; RCB 64 bytes, LnkDisable- CommClk+

Supported Power States
St Op     Max   Active     Idle   RL RT WL WT  Ent_Lat  Ex_Lat

 1 +     7.00W       -        -    1  1  1  1        0       0
 2 +     6.00W       -        -    2  2  2  2        0       0
 3 +     5.00W       -        -    3  3  3  3        0       0
 4 +     4.00W       -        -    4  4  4  4        0       0

So it seems that Micron 7450 MAX doesnt support ASPM meaning if you want them to run cooler you need to manually adjust the powerstate statically.
