"Used to" speaks of PAST habits or states that NO LONGER OCCUR; "usually" speaks of HABITUAL actions or states in the PRESENT (or in a non-specifically past time of reference).
USED TO + infinitive: expresses a PAST HABIT OR STATE that no longer occurs in the present. "I used to go to the gym every morning" = I used to go every morning (I no longer do). "She used to live in Madrid" = she used to live in Madrid (she no longer lives there). USED TO always implies an IMPLICIT CONTRAST WITH THE PRESENT: something that was true before but is no longer. NOT the same as simple past without "used to": "I went to the gym every morning" = I went to the gym every morning (could be a past routine or a one-time action, without the present-contrast implied by "used to"). NEGATIVE: "didn't use to" or "used not to" (formal). QUESTION: "Did you use to...?" (not "used you to").

The onboarding process used to take three weeks; with the new digital platform, new hires are fully operational within their first four days.
USUALLY: frequency adverb indicating something happens in MOST INSTANCES — a HABITUAL pattern. Does not specify that the habit is only past or that it no longer occurs. "She usually arrives at 9 a.m." = she normally arrives at 9 (present habit). "He usually worked late when there was a deadline" = he normally worked late (past habit, without the present-contrast implied by "used to"). USUALLY position: normally before the main verb (after the auxiliary if there is one): "She usually works from home." "They are usually on time." USUALLY can go at the beginning or end of a sentence for emphasis: "Usually, she arrives early."
The steering committee usually meets on the third Tuesday of each month to review project milestones and address any escalated operational issues.

Common mistake
Classic errors: (1) "I use to go" = INCORRECT. The affirmative form is always "I USED TO go" (with final -d). "I use to" only appears in negatives and questions: "Did you USE TO go?" / "I didn't USE TO go." (2) "I am used to wake up early" = INCORRECT. "Be used to" = to be accustomed to and requires a GERUND: "I am used to WAKING UP early." Do not confuse: "I used to wake up early" (past habit) vs "I am used to waking up early" (to be accustomed to waking up early, can be present). (3) "I usually went there" = correct for a past narrative habit, but if you want to emphasize it no longer occurs, "I used to go there" is more precise and natural.
Trick to remember it
The key TEMPORAL DISTINCTION: USED TO = PAST habit or state that CONTRASTS with the present (no longer occurs or is no longer true). USUALLY = habit in ANY TIME, without contrast with the present. Test: do you want to imply something NO LONGER HAPPENS today? = USED TO. "I used to smoke" = I smoked before (I no longer smoke). Are you only describing a habitual frequency without implying it changed? = USUALLY. "I usually drink coffee in the morning" (present habit). "I usually drank coffee in the morning [when I worked there]" (past habit, but "usually" is neutral — does not imply I no longer do it). USED TO always speaks of the PAST. USUALLY speaks of the time frame of reference in the sentence (present, past, or habitual future).
Quick rule
Used to = PAST habit that NO LONGER OCCURS (implies contrast with present). "I used to run every day" (I no longer run). Usually = HABITUAL pattern in any tense, no contrast implied. "I usually run in the morning" (I still do). Never "I use to" in affirmative — always "used to."
Did you know?
The verb "used to" is one of the most curious examples of MORPHOLOGICAL FOSSILIZATION in English: the form "used to" historically comes from the verb "to use" (in the archaic sense of "to be accustomed to"), but in modern English it functions as a frozen SEMI-AUXILIARY. Nobody interprets "used to" anymore as the verb "use" plus the preposition "to" — it is a fixed semantic unit. This explains the confusion with the negative and interrogative forms: when using the auxiliary "did," the verb returns to its base form ("use"), resulting in "didn't use to" and "did you use to?" (no -d). This return to "use to" (without -d) in questions and negatives is what confuses native speakers too: many write "use to" even in affirmative by analogy with the question form. This "grammatical fossil" is an example of how past linguistic habits become trapped in present-day structures.

Used to = PAST habit that NO LONGER OCCURS (implies contrast with present). "I used to run every day" (I no longer run). Usually = HABITUAL pattern in any tense, no contrast implied. "I usually run in the morning" (I still do). Never "I use to" in affirmative — always "used to."
