That's not what I asked for. And that's not the *driver*, that's
the *device*.

For example, this laptop has an Ethernet and a wireless card:
[~] lspci -nn |grep -i net
01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL810xE PCI Express Fast Ethernet controller [10ec:8136] (rev 07)
02:00.0 Network controller [0280]: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter [168c:0036] (rev 01)

and there's no RTL810xE or QCA8565 driver.  The first actually uses the r8169
driver, and the second uses the ath9k driver. Both those drivers support a
wide range of devices.  iwlwifi is another driver that supports a whole bunch
of devices.

Meanwhile, a USB trackball I use is:

[~] lsusb | grep Track
Bus 001 Device 002: ID 045e:0023 Microsoft Corp. Trackball Optical

And those [10ec:8136], [168c:0036], and [045e:0023] are actually important, as
that is what the *HARDWARE* device identifies itself as, and what the kernel
uses to identify which driver should be used to support the device.. There are
many actual instances where the hardware device has both a USB and PCI variant
- and only one or the other is actually supported by an in-tree driver.

And you still haven't told us what driver source you're trying to compile, or
where it came from.
