I accidently deleted the kernel driver related to my hub (docking station): xhci_hcd.

[ 2543.191957] usb usb2-port2: unable to enumerate USB device

Where can I find it?

Thanks.

EDIT:

I accidentally deleted xhci_hcd driver after trying to install realtek usb network driver.

I found out about it When I connected the Hub and it didn't recognized by the OS, so using dmesg command, I got the output: [ 2543.191957] usb usb2-port2: unable to enumerate USB device.

So I looked for usb2 in lshw and got the output:

*-usb:2
             description: USB controller
             product: Tiger Lake-LP USB 3.2 Gen 2x1 xHCI Host Controller
             vendor: Intel Corporation
             physical id: 14
             bus info: pci@0000:00:14.0
             version: 20
             width: 64 bits
             clock: 33MHz
             capabilities: xhci bus_master cap_list
             configuration: driver=xhci_hcd latency=0
             resources: iomemory:600-5ff irq:163 memory:603f260000-603f26ffff

Under the configuration section I saw that the driver needed for the hub is xhci_hcd.

If something is wrong in my research and conclusions, I would be happy to hear.

If the problem is really this missing driver/module, how and where can I get it from?

Is it part of a package?

"deleted the kernel driver" how?

You've provided no actual OS/release details; and if using a Ubuntu system (esp. LTS) there are more than a single kernel stack option thus *kernel modules* (aka *drivers*) can actually differ. If you want to find the code, all are located on launchpad.net (or further upstream too), but we can't be specific as you've provided no OS/release & kernel stack option (*the kernel stack default is set by ISO used to install your system which we don't know*).

@Rinzwind I commented the way it happened. What additional information can I provide ?

Maybe here: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/log/?qt=grep&q=usb

But I think Ubuntu should get the firmware automatically.

What kind of docking station do you have?

I bought this one: https://www.amazon.com/-/he/dp/B0BQ65KG3V/ref=sr_1_8?keywords=%D7%AA%D7%97%D7%A0%D7%95%D7%AA+%D7%A2%D7%92%D7%99%D7%A0%D7%94+%D7%9C%D7%9E%D7%97%D7%A9%D7%91+%D7%A0%D7%99%D7%99%D7%93&s=pc&sr=1-8 The LAN was configured to 100Mbit instead of 1Gbit, so I assumed the problem is with a driver. Downloaded Realtek driver named: r8152-2.17.1 and durring the installation it provided some errors and stucked. After that I realized that this module probably deleted the current one, which was the xhci_hcd.

I cannot open the link.

maybe search the driver on the Vendor homepage?

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.
