Will my UPS interface be recognized --> How to know if my current kernel version will support the class USB CDC-ACM kernel 2.6?

fm flag

I'm running on:

Ubuntu 20.04.2 LTS (GNU/Linux 5.4.0-135-generic x86_64)

I'm seeking out an uninterruptible power supply (known as a no-break where I live) which can shut down linux in the event of energy loss. I've already found some info on https://networkupstools.org/ddl/#_supported_devices.

A manufacturer (NHS.COM.BR) specifies in order for the UPS' USB interface to be recognized, Ubuntu's kernel should support USB CDC-ACM class (NHS says kernel 2.6 or 2.4 "patched"). UPS manual can be accessed on (portuguese): https://www.nhs.com.br/wp-content/uploads/2020/08/Manual-NHSUPS-SW-3.0.30.pdf.

I have been reading some info on https://en.wikipedia.org/wiki/Linux_kernel_version_history; but it seems latin to me.

Prior to purchasing the UPS I should really know if this functionality will be supported by my OS.

Thanks in advance (I am really new to all of this...)

It is always a good idea to check that the device you plan to buy "will be supported by my OS". (Is "my OS"=Ubuntu, or is there another OS?)

Usually, when it says 2.6 or later, it should work with later kernels, including 5.4.0-135-generic.

There is a builtin module cdc-acm.ko available:

find /lib/modules/$(uname -r)/kernel/drivers/ -iname "*cdc-acm*"
/lib/modules/5.4.0-135-generic/kernel/drivers/usb/class/cdc-acm.ko

No umodem or ucom though.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
